I used to do fictional writing a while back, and have always had a keen interest in geology and the study of worlds, so while I may not be writing any more I just wanted to tell you that every single vid of yours I've watched has been a great source of educational entertainment, and it's been making me think more and more about getting back into writing again!
I thought that too, my friend told me about worldbuilding and I had heard that GRRM had used a binary star system for one of his books and so I thought I would choose a different astronomical phenomena... only to find out it was already a popular idea. It hasn't stopped me learning a tonne about geography and biology though and while originality is always good, narratively, having a built world is nothing compared to writing ability. Your world can be boring as hell but as long you have interesting characters and some meaningful text, people will like it.
It's also useful to keep track of prevailing winds if your fantasy (or soft sci-fi) world has any unique airborne stuff...or unique landborne stuff that can be turned into dust, for that matter.
And modifying wind patterns for land mass isn't all that much additional work, usually. The first 2 links in the doobly-doo are for Geoff's Climate Cookbook, though a lot of the same processes have already been covered by Edgar here on Artifexian. The Climate Cookbook is more for the accuracy/verisimilitude focused worldbuilder with extra time. Edgar's technique is a lot more practical.
Equally taking note of global-scale disasters like volcanos, celestial impacts or more modern nukes, antimatter or whatever. Could also help model spread of airborne infections if you're doing some viral outbreak.
Thanks for explaining that part about the Coriolis effect. My geography teachers never bothered to say why it had the three different cells. They just sort of hand-waves it by saying "Coriolis effect" and didn't say why. I studied geography at A-level, but you managed to teach me something interesting in the first two minutes of this video, that is directly related to my geography syllabus that I somehow managed to go 4 years without learning.
I discovered your channel years ago when looking up conlanging stuff, but only recently subbed because these worldbuilding videos are absolutely top notch.
One thing that's worth pointing out here is that the subtropical highland climate can, and does, yield plants well-adapted to temperate climates (despite the subtropical highlands occurring in the tropics themselves). This is why potatoes, a plant that is indeed native to Peru, thrives in e.g. Canada.
I really love these videos. They have inspired me to do so much more worldbuilding. First, I was just making a little island civilisation and I was going to make them a language but now I am going to make a whole world for them and figure out how their weather is and how that will affect their architecture and what types of plants and wildlife they have.
Oh yes, I saw the Catatumbo lightning mention coming when you were talking about Mordor everlasting thunderstorms. It's great to have my country on the spotlight! :D
Nice! Where would you like to go first? I'd suggest Colombia, because it has a very accurate Latin American culture (also it's a lot safer than its Eastern neighbour).
Ratchet4647 I'm pretty sure that if people want to go to a place thinking of the words "Latin America", Colombia may look the most like what they're imagining. I may be thinking stereotypically though (I'm Latin American, however)
BonaparteBardithion since habitable planets will have mostly common gases (carbon dioxide, nitrogen, hydrogen,etc) and gas is transparent ... Light will scatter to the blue spectrum hence thats why it would be the most common color. I could be wrong though
You really have good instincts for when and how concepts need visual representation. You explain just enough but not too much. And it's really nice that you reused the world you made before. It really helps tie things together in my brain.
A little late to the party but this specific video has saved my life as a writer. Currently working on a world & story heavily featuring sailing and diverse island ecologies, and this is exactly the starting point I needed for setting up the global climate. Awesome stuff.
Glad to see that here at Artifexian we follow the Cave Johnson School of Projectile Sciences: "We fire the whole bullet! That's 65% more bullet per bullet!"
Wow, I need to go and look more into this, it's quite interesting! Also having just watched the Hello Internet podcast on Guns, Germs, and Steel, I heard you say Jared Diamond and just reflexively sighed, so that's a thing too. Great video, I love your worldbuilding series!
Another fun fact about tornadoes. They can only really happen in plains like areas. The wind needs an even ground, otherwise there would be too much disturbance and couldn't keep it's shape.
You've posted some great videos on astrophysics, geography, language and a bit of vexillology, but do you think you'll ever do something on biology? Evolution, ecology, something like that? I think it'd be met with positivity by your current fans, but also attract a whole new audience of people. Since some spend a lot of time in their worldbuilding developing things like fauna and flora, I was wondering if you'd post any content on that too.
Don't mind the historians. Jared Diamond's book, Guns Germs and Steel, has inaccuracies but it's still brilliant. Well done in getting that key point of animals and crops not crossing zones clearly explained.
"Empires are more likely to do their empiring in zones similar to their homeland." I feel like this is how they should teach this content in schools. Simple, and to the point.
So happy to see Pixie and Azelor's tutorials over on the Cartographers' Guild referenced in the description :D Expanding massively on Bricka's "Creating and Earth-like Planet" (I think that was the title), which is sadly now fairly difficult to find online from what I can remember, they've put so much work into creating something easily accessible to the world-builder and which is easy to follow :)
I just realized my first fictional planet had continents almost entirely in the Temperate Zone, but had an average temperature of only 11 Degrees. Makes me wonder just how cold the north and south cold zones would be, and if the Hot Zones would be considered what we call ‘Room Temperature’.
I like that this counts as studying Like that's not even a stretch or exaggeration I have exams in Global Change and Introductory Marine Geology over the course of the next 1-2 weeks and this is important in both of them.
Yeah - for example, the ITC follows (with a time lag of a few weeks, and distorted in shape by the landscape) the latitude where the sun is in the zenith over the seasons - thus, your planet's axial tilt determines the limits of latitude within which it will move, and thus also the latitudes of the cells associated with it.
No the cells are not effected by axial tilt. Think about it, in the video the number of cells increased the faster the planet rotated irregardless of axial tilt. Axial tilt will determine the locations of the tropics of cancer and capricorn and the artic circles not the cell boundaries. On Earth these happen to be the same but just look at jupiter. Axial tilit plays a role in seasonality not in the latitudanal extent of the cells.
Thank you so much for this video and the links in the subscription... thanks to them I finally got some motivation to get back to my current fantasy world after a few months of having none and now with the tutorials I will be able to know so much more about it:) I hope you will give me many more inspiration in the future. Still at the stage of drawing my second detailed wind map. Doing something right really does take a lot of time... but I think it will be worth it. Heck it already is:)
Awesome video it is a very complicated subject but you did a good job pulling out the basics. Only thing I 'd have mentioned explicitly would be the descending cells being dry even if it might be self explanatory for some mostly to be consistent (as you mentioned similar processes for tidally locked worlds.
As I understand it, you can't have just one big Hadley cell in each hemisphere (as shown at 3:04). Surface winds would be easterly all over the world, so there would be a net eastward force on the atmosphere as a whole. Surface drag has to balance between easterly and westerly zones. Slower rotation would tend to eliminate the polar cells, though, and to weaken the global zonal pattern relative to more localized patterns like land/shore circulation and the somewhat analogous patterns around differences in altitude.
I’m building a fantasy world, called Pentrine, that’s actually just a few continents ringed by massive walls. These concave walls are roughly two miles high, with opaque “curtains” rising off them that reach into the upper atmosphere. No wind can travel over or through these curtains. I’m having difficulty finding reputable sources that discuss such fantastical ideas. Would they create enormously powerful downdrafts or updrafts depending on location and season? Would they be raked with constant storms and tornadoes? I have no idea. But I need to figure out the gist of it by saturday, and it’s fun to think about. Thanks for this video.
I was waiting for the shoe to drop on Lake Maracaibo as you described your modified Mordor. "That description is starting to sound like that one lake in South Amer- there it is."
Quick Question: The world I'm working on has an axial tilt of 60 degrees. So, The tropics and the poles are switched. Would this effect the direction of the cells? Like winds would move upward towards the tropical poles, or would nothing change?
I would recommend checking out David J Peterson's channel (as well as his book, THE ART OF LANGUAGE INVENTION) he's a professional conlanger and is the creator or Dothraki and High Valyrian both from Game of Thrones, the languages from Defiance, the language in Marvel's Thor; The Dark World, as well as many others.
just thought of something The stormlands of ASOIAF is bordered to the south by mountains, to the east by the sea, and just north of a desert. It's aptly named
The western coasts at 60° latitude (with an Earth-like rotation rate) tend to get a lot of precipitation, especially if there’s a nearby mountain range to the east. This is why Bergen is so famously rainy.
This is something I really would not have thought about on my own! Turns out one of my character's country would be a really crappy place to live... Really hot, frequent storms, hurricanes, so I might need to tweak that! Other than that, how would the planets rotation angle affect this? If my world's is tilted roughly 10 degrees, how does that work?
tilt affects how seasons work. bigger tilt = bigger daytime/nighttime change between summer/winter. Bigger tilt also means the planet is colder overall, because winters are colder = more snowfall which reflects more sunlight. Summers also get hotter, which means they radiate more heat away. The size of the polar caps may also affect oceanic currents, if one or both of the caps at least partially covers an ocean. Water can transfer much more heat than winds. They follow the same rules as atmospheric circulation, except there may be continents in the way. In combination with the excentricity of orbit it also affects which hemisphere is colder. When planet is closer to the sun it moves faster, so that season will be shorter and vice versa. In case of earth, it is closest to the sun in January, which is why winters are shorter in the northern hemisphere.
Im not an expert, but im making a world that also has a 10 degree tilt so heres my guess. As the tropical belt isnt as large (because of the lower tilt) the very hot area around equator would be smaller and not as hot. This would probably mean milder weather compared to here on earth but tropical storms would still happen. This is also affected by the placement of your oceans and landmasses as storms tend to die out once they hit land. Im guessing the general lower temperatures from the lower axial tilt would result in tamer weather, but it depends on a lot of things that im not qualified to answer with my high school C-level natural geography.
Mathias Hansen Okay, that seems good. I was scared I would have to change large parts of my setting because of something so arbitrary as winds and stuff.
I live bingewatching these videos just in case I ever write a super detailed novel and maybe by then I'll have watched them often enough to get what you're saying (not on you, you're amazing, I'm just too dumb to get it)
And much like portal turrets, you shoot the whole bullet, casings, powder and all. More bullet per bullet. That mistake always makes me laugh, loving your videos though!
2:30 - the planet "spinning in the opposite direction" is just a matter of perspective, isn't it? Like a rotated map. I mean, I guess weather would be different if the direction was reversed on a given map (maybe it would effect whole ecosystems), but it wouldn't make a fundamental difference between the planets, right?
Yes, direction is a matter of perspective but it would make a fundamental difference between planets as along as observers on each planet are using the same reference frame. If there all measuring off the same fixed point they notice that winds blow in different directions on different worlds if the rotation is different.
But you'd only notice that if you reversed the direction for a given geography, right? Unless there's some universal way East and West would be defined on other planets? I assumed East would just by definition be the direction from which the sun rose, but now I'm not sure :P
grogdizzy it's easy enough. World maps with Antarctica at the top exist, then you just flip every N/S when it comes to magnets etc, while swapping north/south and east/west pairs for directions... Nothing else actually changes, at all. Bonus: maps used to be drawn with the East at the top. (The origin of the term "Orient" for places east of Europe, actually.)
Well, more or less; in polar regions the sun can rise and set in the north and south at certain times of the year. I live in such a place; the sun is up 24 hours now, but in July it will be rising and setting in the north briefly. But otherwise yes; if you at the equator of a planet that's oriented so it's spin axis is roughly perpendicular to its orbital plane and the rotation is prograde, during an equinox and face the rising sun, East is in front of you, West is behind you, North is to your left, and South is to your right.
Britain had a very large empire in the tropics, but the places that were settled in a big way i.e. The US, Canada, Australia, New Zealand, Northern Ireland, and South Africa are all wholly or partly in the temperate zones, and Australia and Canada have their populations concentrated in their most temperate parts. Even in India, New Delhi is in the far North of the country and the British enclave at Shimla was right up in the Himalayan foothills.
Awesome worldbuilding video. I've been kinda stuck on one of my maps because I want to know where crops should be able to grow and what types of other plants & animals will naturally be in different regions.
Artifexian hahahahah YOU BET they'll draft you so badly, you won't be able to defend yourself anytime soon. next thing you know, you're a full-time flattard explorer (with a Prussian helmet), sent out to check the world's edge, and if the turtle has awakened. "turtle? there is no turtle, this world is carried by a disabled toothless crocodile" yeah, well, worldbuilding...
I have a flat and circular world (a la Discworld) and first you need to figure out how your sun is moving. Is it looping over and under your world? Is the world itself spinning? You'll get different insolation patterns depending. For example: if lopping and spinning, you'll get a circular pattern of insolation like the center of your world is the north pole and the outer rim is the south pole. If looping and stationary you'll get horizontal bands across the world. Or, you could "cheat" and have the sky basically be magical (an illusion or construct) and you can get any kind of variation on a circular pattern you want.
Interesting video as always, and especially in how the orbital characteristics, especially something as mundane as a planet's rate of rotation connects to how the ecosystem and culture of a planet. Nice to see that there are benefits and consequences for all those orbital mechanics and planet types and would love to see more of these interwoven videos. Speaking of rotation rates, also interesting to see how it determines the atmospheric cells of a planet or at least the number per hemisphere. Definitely something GURPS Space 3rd Edition didn't cover in their planet creation mechanic as far as I can recollect. If anything, it does help with planning the iconic bands for gas giants and ice giants. Now how to work out all those red/dark spots aka Jupiter and Neptune and that hexagonal cell at one of Saturn's pole.... As for placement of flora and fauna into different biomes based upon latitude and cell along with spreading of civilizations and empires, sounds like a useful tool for at least generalizing what goes where and how far, though I can only surmise that the temperate zones would allow the equatorial/polar lifeforms to survive, just not thrive as within their native latitude. Same can be roughly said of temperate life forms transplanted to those other altitude locations, though naturally there will be some variations as to how well in each. As for the spread of civilization/empires, I can also assume that advancement in technology make that a bit easier to spread to other latitudes, but useful in blue printing cradle civilizations and other such historical nations/empires. Though now that I think of it, diseases and their vectors can also be mapped out based upon the altitude as well. What with more tropical variants being spread more widely spread through parasites year round while the more temperate (and arguably polar) latitudes being more seasonal due to the winter season and close proximity to one another and livestock. Probably oversimplifying the whole thing, but it does leave food for thought in the case of worldbuilding. Either way, thanks for this newest video upload Edgar.
The round casing doesn't follow the bullet on its trajectory, Edgar, it gets ejected. It was jarring watching the whole thing travel north after supposedly being fired.
5:11 well, this is correct, but also wrong, i will explain, in my state, in the middle of the equator, when we plant our grapes and other fruits from temperate zones they actualy not only grow faster and are more candy than the mades in the south of the country, who is in a temperate zone, but they also are better than the majority of the made in EUROPE, so is like, the more sun light that the plant can take is better, they can spend more energy, because they have more than they temperate counterparts, in things like grown faster and also make more candy fruits, this means that the consideration is aldo wrong, but putting a lot of tropical fruits like bananas in Canada will make they die, because of is too cold at winter and they would receive few light.
More stuff I've been loathe to work out. Well, now I must figure out how this will work with a torodial world. Offhand guess: The rimward side would operate much as any spherical world, except for the polar region. The polar rings would operate similarly to the tidally-locked world. Figuring out the hubward side is where my mind breaks.
"The U.S. is a great example" D: *cries in harvey and ike* the rain and storm patterns of southeastern Texas have been likened to monsoon like conditions. R.I.P. I guess storms thrive in our bipolar weather.
I use OneNote to write these things down as a personal reference book. You could do something like that. :D I also find it easier to understand what's being said that way.
actually, fun fact, lighting impacts soil fertility since the intense electrical output can condense nitrogen into usable forms in the soil. Hence why so many religions native to more extreme temperate/boreal regions value the thunder god so much, lighting was the only thing nitri-fying the soil there, granted they just figured out "hey when lightning strikes we don't have fertility issues." but it'd definitely be a cool thing to mess with culturally in a thunderstorm ridden world where the soil and climate is the best for promoting soil fertility.

Would the tilt of the planet effect the latitudes of the cells?
Yep. The tropics, or subtropical ridges, would have the same latitude as the axial tilt, and the polar fronts would have a latitude of (90 - tilt).
Yeah - for example, the ITC follows (with a time lag of a few weeks, and distorted in shape by the landscape) the latitude where the sun is in the zenith over the seasons - thus, your planet's axial tilt determines the limits of latitude within which it will move, and thus also the latitudes of the cells associated with it.
On a micro scale
Kevin Gillette
Cells are made by rotation
The tilt affects only the borders, making them move north-south during the year
No the cells are not effected by axial tilt. Think about it, in the video the number of cells increased the faster the planet rotated irregardless of axial tilt.
Axial tilt will determine the locations of the tropics of cancer and capricorn and the artic circles not the cell boundaries. On Earth these happen to be the same but just look at jupiter.
Axial tilit plays a role in seasonality not in the latitudanal extent of the cells.
That was awesome. Also I love having application to fantasy and then reality. That really brings it all home.

As I understand it, you can't have just one big Hadley cell in each hemisphere (as shown at 3:04). Surface winds would be easterly all over the world, so there would be a net eastward force on the atmosphere as a whole. Surface drag has to balance between easterly and westerly zones.

Would they create enormously powerful downdrafts or updrafts depending on location and season? Would they be raked with constant storms and tornadoes? I have no idea. But I need to figure out the gist of it by saturday, and it’s fun to think about.
Thanks for this video.
Congrats on hitting 100k subs
Great episode mate
Thx :)
I was waiting for the shoe to drop on Lake Maracaibo as you described your modified Mordor. "That description is starting to sound like that one lake in South Amer- there it is."
How have these videos not got more attention and followings?!
Awesome video , at least the third time I've seen this ... keep it up
Quick Question: The world I'm working on has an axial tilt of 60 degrees. So, The tropics and the poles are switched. Would this effect the direction of the cells? Like winds would move upward towards the tropical poles, or would nothing change?
Epic info as always!
Also, happy 100k subs!
So, when are you going to tackle verb conjugations for conlanging?
Soon. Within the next couple of videos I reckon.
Could you also cover the different forms of tenses and maybe the implications for the perception of time? That's something I'm always interested in!
+Kijnn The tenses your language has have no effect on how you perceive time.
I would recommend checking out David J Peterson's channel (as well as his book, THE ART OF LANGUAGE INVENTION) he's a professional conlanger and is the creator or Dothraki and High Valyrian both from Game of Thrones, the languages from Defiance, the language in Marvel's Thor; The Dark World, as well as many others.
Artifexian Awesome! I look forward to it
Great videos. I've learned so much from this.
It is awesome!
Thanks!
Damn, just the i wished a new video on climate ^^
Hope you like it.
"A Peruvian crop planted in Canada will mostly likely died"
Highlands crops in the tropics: "I'm about to end this man's whole career"
just thought of something
The stormlands of ASOIAF is bordered to the south by mountains, to the east by the sea, and just north of a desert.
It's aptly named
I was actually looking for this
The western coasts at 60° latitude (with an Earth-like rotation rate) tend to get a lot of precipitation, especially if there’s a nearby mountain range to the east. This is why Bergen is so famously rainy.
This is something I really would not have thought about on my own! Turns out one of my character's country would be a really crappy place to live... Really hot, frequent storms, hurricanes, so I might need to tweak that! Other than that, how would the planets rotation angle affect this? If my world's is tilted roughly 10 degrees, how does that work?
tilt affects how seasons work. bigger tilt = bigger daytime/nighttime change between summer/winter. Bigger tilt also means the planet is colder overall, because winters are colder = more snowfall which reflects more sunlight. Summers also get hotter, which means they radiate more heat away.
The size of the polar caps may also affect oceanic currents, if one or both of the caps at least partially covers an ocean. Water can transfer much more heat than winds. They follow the same rules as atmospheric circulation, except there may be continents in the way.
In combination with the excentricity of orbit it also affects which hemisphere is colder. When planet is closer to the sun it moves faster, so that season will be shorter and vice versa. In case of earth, it is closest to the sun in January, which is why winters are shorter in the northern hemisphere.
Im not an expert, but im making a world that also has a 10 degree tilt so heres my guess.
As the tropical belt isnt as large (because of the lower tilt) the very hot area around equator would be smaller and not as hot. This would probably mean milder weather compared to here on earth but tropical storms would still happen. This is also affected by the placement of your oceans and landmasses as storms tend to die out once they hit land.
Im guessing the general lower temperatures from the lower axial tilt would result in tamer weather, but it depends on a lot of things that im not qualified to answer with my high school C-level natural geography.
Wouldt high tilt woulds generally be warmer overall, considering the more evenly distributed sunligt it gets?
Mathias Hansen Okay, that seems good. I was scared I would have to change large parts of my setting because of something so arbitrary as winds and stuff.

Thank you! I will make sure to figure some more of this out, I'll try to make it work! (I am disorganized, don't judge me)
I live bingewatching these videos just in case I ever write a super detailed novel and maybe by then I'll have watched them often enough to get what you're saying (not on you, you're amazing, I'm just too dumb to get it)
6:25 "This would not have been a great route to take"
Portugal in 1497: "How about I do anyway?"
And much like portal turrets, you shoot the whole bullet, casings, powder and all. More bullet per bullet. That mistake always makes me laugh, loving your videos though!
has he ever shown us his fictional universe(s)? his videos are specifically to show us how to make our own, but where is/are his?
2:30 - the planet "spinning in the opposite direction" is just a matter of perspective, isn't it? Like a rotated map. I mean, I guess weather would be different if the direction was reversed on a given map (maybe it would effect whole ecosystems), but it wouldn't make a fundamental difference between the planets, right?
Yes, direction is a matter of perspective but it would make a fundamental difference between planets as along as observers on each planet are using the same reference frame. If there all measuring off the same fixed point they notice that winds blow in different directions on different worlds if the rotation is different.
But you'd only notice that if you reversed the direction for a given geography, right? Unless there's some universal way East and West would be defined on other planets? I assumed East would just by definition be the direction from which the sun rose, but now I'm not sure :P
grogdizzy it's easy enough. World maps with Antarctica at the top exist, then you just flip every N/S when it comes to magnets etc, while swapping north/south and east/west pairs for directions... Nothing else actually changes, at all.
Bonus: maps used to be drawn with the East at the top. (The origin of the term "Orient" for places east of Europe, actually.)
East is, by definition, the direction from which the sun appears to rise.
Well, more or less; in polar regions the sun can rise and set in the north and south at certain times of the year. I live in such a place; the sun is up 24 hours now, but in July it will be rising and setting in the north briefly. But otherwise yes; if you at the equator of a planet that's oriented so it's spin axis is roughly perpendicular to its orbital plane and the rotation is prograde, during an equinox and face the rising sun, East is in front of you, West is behind you, North is to your left, and South is to your right.
This planet looks awesome!
Britain had a very large empire in the tropics, but the places that were settled in a big way i.e. The US, Canada, Australia, New Zealand, Northern Ireland, and South Africa are all wholly or partly in the temperate zones, and Australia and Canada have their populations concentrated in their most temperate parts. Even in India, New Delhi is in the far North of the country and the British enclave at Shimla was right up in the Himalayan foothills.
Great point.
Don't for 5 the various colonies on isles in the southern sea like the Falkland's and maybe the south sandwich islands
Awesome worldbuilding video. I've been kinda stuck on one of my maps because I want to know where crops should be able to grow and what types of other plants & animals will naturally be in different regions.
What about weather patterns on a flat, circular wold? It's cold in the north, hot in the south, and the water runs off the world disk at the edges.
I'd like to make a flat planet video but I feel bad because it'll most certainly get co-opted by flat earthers. Perhaps one day.
Artifexian hahahahah YOU BET
they'll draft you so badly, you won't be able to defend yourself anytime soon.
next thing you know, you're a full-time flattard explorer (with a Prussian helmet), sent out to check the world's edge, and if the turtle has awakened.
"turtle? there is no turtle, this world is carried by a disabled toothless crocodile"
yeah, well, worldbuilding...
the crocodile's name is Znory btw
I'll show myself out...
I think a flat world would be an incredibly interesting conworld, it's just that posting any videos about it would be honey for flat earther flies.
I have a flat and circular world (a la Discworld) and first you need to figure out how your sun is moving. Is it looping over and under your world? Is the world itself spinning? You'll get different insolation patterns depending. For example: if lopping and spinning, you'll get a circular pattern of insolation like the center of your world is the north pole and the outer rim is the south pole. If looping and stationary you'll get horizontal bands across the world. Or, you could "cheat" and have the sky basically be magical (an illusion or construct) and you can get any kind of variation on a circular pattern you want.
very informational and helpful, thank you
Yes a sequel
A third instalment is in the works.
Interesting video as always, and especially in how the orbital characteristics, especially something as mundane as a planet's rate of rotation connects to how the ecosystem and culture of a planet. Nice to see that there are benefits and consequences for all those orbital mechanics and planet types and would love to see more of these interwoven videos.
Speaking of rotation rates, also interesting to see how it determines the atmospheric cells of a planet or at least the number per hemisphere. Definitely something GURPS Space 3rd Edition didn't cover in their planet creation mechanic as far as I can recollect. If anything, it does help with planning the iconic bands for gas giants and ice giants. Now how to work out all those red/dark spots aka Jupiter and Neptune and that hexagonal cell at one of Saturn's pole....
As for placement of flora and fauna into different biomes based upon latitude and cell along with spreading of civilizations and empires, sounds like a useful tool for at least generalizing what goes where and how far, though I can only surmise that the temperate zones would allow the equatorial/polar lifeforms to survive, just not thrive as within their native latitude. Same can be roughly said of temperate life forms transplanted to those other altitude locations, though naturally there will be some variations as to how well in each. As for the spread of civilization/empires, I can also assume that advancement in technology make that a bit easier to spread to other latitudes, but useful in blue printing cradle civilizations and other such historical nations/empires.
Though now that I think of it, diseases and their vectors can also be mapped out based upon the altitude as well. What with more tropical variants being spread more widely spread through parasites year round while the more temperate (and arguably polar) latitudes being more seasonal due to the winter season and close proximity to one another and livestock. Probably oversimplifying the whole thing, but it does leave food for thought in the case of worldbuilding.
Either way, thanks for this newest video upload Edgar.
No probs pal. Apologies it took so long in getting out.
Artifexian So long that it's out, I'm fine.
The subtropics are at the meeting point of the Ferrel and Hadley cells, which is why weather patterns there change directions every six months.
Hey, Artifexian!
Howdy.
The round casing doesn't follow the bullet on its trajectory, Edgar, it gets ejected. It was jarring watching the whole thing travel north after supposedly being fired.
Edgar follows the Aperture Science method and fires 65% more bullet per bullet.
Haha! I actually had no idea this happens. Have never shot a gun before.
It's an easy mistake to make if no one has explained the mechanics to you, I just thought it was funny. I love your videos keep up the good work!
5:11 well, this is correct, but also wrong, i will explain, in my state, in the middle of the equator, when we plant our grapes and other fruits from temperate zones they actualy not only grow faster and are more candy than the mades in the south of the country, who is in a temperate zone, but they also are better than the majority of the made in EUROPE, so is like, the more sun light that the plant can take is better, they can spend more energy, because they have more than they temperate counterparts, in things like grown faster and also make more candy fruits, this means that the consideration is aldo wrong, but putting a lot of tropical fruits like bananas in Canada will make they die, because of is too cold at winter and they would receive few light.
How would the atmospheric Circulation change if the planet has a tile greater than 54 since the tropics and polars would be swaped?
@Artifexian where did you get the latitudes and number of cells for varying earth rotation speed? I searched a lot but never found any information.
More stuff I've been loathe to work out. Well, now I must figure out how this will work with a torodial world.
Offhand guess: The rimward side would operate much as any spherical world, except for the polar region.
The polar rings would operate similarly to the tidally-locked world.
Figuring out the hubward side is where my mind breaks.
"The U.S. is a great example" D: *cries in harvey and ike* the rain and storm patterns of southeastern Texas have been likened to monsoon like conditions. R.I.P. I guess storms thrive in our bipolar weather.
Would love you to do a video on Game of Thrones - your best explanation for the chaotic cycles of summers and winters.
THE BEACONS ARE LIT!
This is epic however I think it would be cool if you did a video explaining the effects different rotations speeds would have on a planet.
I would buy a book of your collected knowledge as a reference book
I use OneNote to write these things down as a personal reference book. You could do something like that. :D I also find it easier to understand what's being said that way.
We have finally proven that Venezuela is basically Mordor. I'm so proud of what we've achieved
actually, fun fact, lighting impacts soil fertility since the intense electrical output can condense nitrogen into usable forms in the soil. Hence why so many religions native to more extreme temperate/boreal regions value the thunder god so much, lighting was the only thing nitri-fying the soil there, granted they just figured out "hey when lightning strikes we don't have fertility issues." but it'd definitely be a cool thing to mess with culturally in a thunderstorm ridden world where the soil and climate is the best for promoting soil fertility.
