❤️ Thanks for watching everyone. It means a lot. ❤️ - Розваги
Rainforests get most of their rain from the plants breathing and that moisture condensing. Rainforest literally perpetuate themselves and that means they can grow too. The extra rain let’s more plants grow around rainforests which creates more rainforest. So rainforests will usually fill a geologic basin even if it looks like it should have been savanna.
Hopefully he'll cover that in his biomes video
Plz artifexian see this
I agree you here lol
That still doesnt make it rainforest climate though! The eastern amazon rainforest is wet, however it is almost entirely Aw (and a bit Am) climate
You’re right. That’s why Artifexian kept correcting himself when he said rainforest instead of rainforest climate zone. Because climate zones don't always match up with the biomes within them.
I would personally say that the "unclean" psrts of the msp make waaay more sense if you consider the scale of the world. What looks like a small chunk of rainforest on the map is the size of a small country.
First ice caps, then jungles. Artifexian is going all over the place!
The A and E climate zones are by far the most straightforward to map. It's much easier to fill in as you go from there.
Starting at the extremes and working his way to the in-betweeny bits.
11:30 This little “monsoon peninsula” isn’t unrealistic if you look at a map of Earth, lots of climate zones have very jank or fractally boundaries
yeah and it would make for a cool geographic feature
@dzindevis5078 hmm I see… this type of thing makes me feel like the whole methodology is not very good, and more of it should be automated with code. of course no matter how detailed you are it’s possible to be more detailed, so, whatever
10:43 I would extend the monsoons area up farther into the Southern, lower elevations of that seasonally wet region. The not-Andies are going to catch a lot of moisture during the wet season giving you... Monsoons.
11:38 I also would take your Monsoon Italy as a sign that you need a larger Monsoon zone. Instead of getting rid of it, maybe carve out a bit more of the rainforest in the north of the peninsula. Your transitionary Monsoons are already a bit dinky.
Also something to keep in mind for A and C climates/Rainfall:
Now that you have your rajnforests mapped, you should account the Amazon-Andes effect. The moisture that comes from the Amazon travels down to ~ 30 degree South via winds that hit the Andes and travels inland in to South America. The moisture travels over 4 thousand kilometres and precipitates near the subtropical high. I don't quite know if this applies to Kretak, because it is a very specific quirk of the shape of our continent. Maybe the north parte of Picard, i dont really know. However, I'm not a geographer or climatologist, im just an agronomist who lives in the 30S of latitude in South America. But this phenomenon brings LOTS of rainfall (check Rio Grande do Sul floods in 2024), even thru winds that come from inland (offshore). Please check that with rossbaygeo. Again, not an expert in geography, expert with enduring Cfa climate in times of climate change (aka rainfall warzone).
Really really good job on tropical climate!!
First Atlas Pro drops an exomoon video, and now we get tropical climates with Artifexian. Very worldy day today.
Still not as weird as the Baader-Meinhof evening I had last Saturday night, where I talked about the Street Fighter 2 Where's Wally? book while witnessing the chaos occurring in Taiwanese parliament, then saw an image of a drunken E Honda being approached by a JoJo Villain Mister Clean, and finally saw a Street Fightery clash happening on an arcade screen in Little Kitty, Big City. That was a strange time indeed.
Pretty stunning that Picard not only has the coldest and most extreme glacier zone, but also the world's largest tropical rain forest.
I would say that India would probably serve as the prototypical tropical monsoon climate probably! Unless I'm mistaken and it counts as a rainforest.
Great to see a new Artifexian vid!
India is usually the typical example of that yeah
Judging from the map on the Köppen climate classification Wikipedia page, there's a strip of tropical monsoon climate running down the west coast of India; more of it actually appears to be tropical savanna, with a chunk of semi-arid climate inland. Not sure whether I'm reading the map correctly, though.
The rain shadow of the Western Ghats Mountain Range weakens the monsoon over much of Tropical India. As a result, most of India is actually Tropical Savannah, except for the West Coast. By the time we get out of the rain shadow and we get to the monsoon climates again, we are in the subtropics, which is why Cwa basically only exists in India
LETS GOO! JUNGLES!!
I feel like most of this planet is just polar and tropical and there is a thin band between, these temperature differentials are going to create HUGE wind storms.
6:27 i think if you set it to like half opacity, you'd get 4 distinct colors and wouldn't have to toggle it frequently. also could use a high frequency pattern as a mask, and look for areas where it's solid blue. i've been doing all the climate stuff and temp stuff and all that in blender and i made node groups to create grid/circles patterns for blending layers with less opacity confusion.
also, i think blender could do all of the temp mapping for you and identify climate zones, provided continentality, temp offset, and wetness are painted in smoothly, but i've only gotten partway thru that. the temp maps i have so far look great (during the seasonal extremes at least, i might change some of the nodes to improve the in between because it makes automatic isotherms super messy).
I tried the opacity thing but for me it got very cluttered and I could make out what was going on. But that's me, others might get more joy with it
You can pretty easily translate temperatures and precipitation into climate zones using the select tool. Select the range of acceptable temperatures and fill in that selection on a new layer, select the range of acceptable precipitation and fill that in on a new layer, then select the intersection of the temperature fill and the precipitation fill and that's the climate zone. Afterwards, you can clean up the edges of the zones if you want.
i have since gotten blender to pick climate zones for me, i highly recommend it. i also have it doing most of the heavy lifting on temperature as well. eventually i’d like to make a blender project file which just has that stuff and empty spots for textures so it’s relatively drag and drop for others to use
That isolated dot of Northern rainforest is exactly the kind of thing ons would expect. Worst case? Expand it a scootch. Best case? Leave it alone.
Can you explain why it's something we would expect?
@@Artifexian you've arranged Temps and rainfall such that you ended up with a microclimate. Where that sits it virtually has to be on a windward side of a mountain range, so you'd get a pocket rainforest surrounded by savanna in the same sort of way you get high elevation tundra or a patch of hot desert on the leeward side of a mountain, but if situated in a peculiar way it could be really close to, say, a monsoon climate.
Part of the point of this exercise is to have a naturalistic world, and when you look at a real, regional scale climate map, there's many isolated pocket climates scattered about, particularly near mountains.
@@Artifexian But it's really just a feeling that nature is messy and can surprise you.
9:20 - There are several places on Earth where Af climates stretch up to the 18°C isotherm, Florida is one such example. The restrictive definition of Af specifically (that the driest month has >60 mm of rainfall) usually causes it to be placed in the wettest parts of rainforests as opposed to in all the regions where you'd typically see rainforests (refer to the Congo Rainforests) leads me to think that the region along that peninsula would probably not be entirely Af. I could see an Af-Am boundary there stretching along the interior from the westernmost point of the original black triangle down southwest in a sort of arcing pattern, with everything south and east of that boundary being Af, instead of the mostly east-west boundary that was drawn in the video. That's just me though.
12:10 - The only conditions in which a direct Af-Aw transition zone is possible is below 1000 mm/year of precipitation, where the precipitation threshold required for an Am-Aw transition zone to exist actually exceeds the 60mm restriction on the driest month. On that same note, it is possible to get a transition zone between an Af and a BSh (Hot Semi-Arid) climate if the Mean Annual Temperature exceeds 36°C, and the driest month has at least 60mm of rainfall. It's extremely rare and doesn't occur anywhere on Earth, but it COULD be possible! The temperature threshold there could theoretically be lowered with certain precipitation patterns, but that'd also involve making the climate a lot wetter.
You know I've been looking at the Köppen climate map of earth for literal years more and I never noticed Florida! That's so cool.
@4:15 "it's really hot; it's really wet"
Same
HE DID IT!!!! AAAAAAA MY CURRENT HYPERFIXATION IS ACTUALLY THE KOPPEN CLIMATE SCALE AS A WHOLE BUT ESPECIALLY TROPICAL RAINFORESTS! AND THIS IS ONE OF MY COMFORT CHANNELS!!
I don’t think there’s anything wrong with the mini rainforest spot tbh
Monsoon Italy could have been a really cool climate pocket with plants and animals different from the surrounding forest, but we can paint over it to make nice smooth line sure
I protest, I do care about the 2 subtypes of tropical savanna, it's half my country's geography!
you don't have to go through that trouble though.
Damn, didn't know you were Canadian
@@nicoruppert4207 I don't get the joke. My guess is because of Edgar's mishap calling Africa Canada?
I am not from anywhere in Africa, I am from Venezuela.
@@alecity4877 It the same one is square and other is square from where monsoon climate is in both continents
New worldbuilder’s log lesgo
Another great video! I appreciated the reminder of the glory and wonder of glaciers, even in a video about the tropics 😂
Loved your society types video! I want to watch one of your conlang live streams when I get the chance! Your content is great for worldbuilding realistic worlds without some of the tediousness of Artifexians models.
@@FanFive5 I'm streaming this Wednesday! And then I'm not sure when the next one will be, but I'd love to have you! And everyone has their own styles, so it's good watching a lot and finding what works best for you ☺️ I love all of Artifexian's stuff but I definitely can't do all the math and 3d modeling and blender haha
@@madelinejameswrites Agreed 😄Blender is a monster of its own.
Hehe
Hell yeah BROTHER!💯🗣️🔥
I got some potentially good news earlier and now there's a new Artifexian video?! I feel so spoiled! :D
Tropics looking awesome. Looking forward to the deserts!
I am appalled that you called Africa Canada but anyways Great video love where this series is going i am jumping up and down with glee knowing that soon we will be moving on towards the next parts of the project! Luv your vids :D
Brain fart
Keep the climate zones interesting! Don't let Earth influence you too much, you're making a new world! This all looks very believable so far!
That mountain range on the southern coast of Degra doesn't look nearly tall enough to be able to black most rainfall further inland. Along with prevailing easterly winds further north, as well as the fact that is is right on the equator, I'd say most of Degra would be tropical rainforest or monsoon with maybe some savanna further towards the poles.
Also I think you extend your savanna too far north on the west coast, I think a lot of that region (particularly on Esri and Jannar) would be hot semi-arid (BSh). Even if it is wet during the summer, you have to consider that high temperatures, as well as mostly summer rainfall, play a part in increasing the amount of rain needed to avoid an arid or semi arid climate.
You would think so, but even a relatively modest mountain range can have a significant rain shadow. The prototypical example on Earth would be the Western Ghats in India
@@mvalthegamer2450 Not really, the Western Ghats only produces a moderately sized semi-arid area immediately leeward. With Tropical savanna dominating the rest of southern India. Even so, India has a mostly savanna climate because of the intensity of the Indian monsoon cycle. Degra doesn't have nearly as strong a monsoon, so I find it hard to imagine inland Degra being dominated by deserts, especially so close to the equator.
I can see Degra going either way. If its rainforests expand themselves inland I don't think it'd be hard for the humidity in the centre to rise enough for the savannahs to merge, but it also reminds me of Africa and slightly less strongly Australia, so I could see a central desert with some light scrub dotting it. Though I think it'd be reasonable to class it as either a humid Steppe or highly seasonal Savannah, possibly even a Cfa or Cwa climate like in southern India or central Ethiopia, though far larger. Though I'd have to study the map and KCC more in depth to be sure.
There will absolutely be a desert in northern Degra. The question for me is whether or not the region behind the those mountains is savannah or steppe.
I'm really looking forward to when you start looking at local places and the ecosystems there. I'm especially curious of the cold plateau of Ezri and the volcanic region of Jannar
Canada, the 8th, secret, continent.
And bigger than that huge continent
These are getting so fun! I can't wait to see it all come together with all the zones
NEW VID!!!!!!!!!!!!!!!!!! can't wait to watch
For the longest time I thought "shocker" was some unique regional word I wasn't familiar with. I don't know why I kept hearing "shakhar" and I wasn't connecting it to "shocker"
awesome video as always but i would like if in the future you showed a timelapse of adding the climates for the entire world
You know that would be great idea, had a thought of it before doing starting these climate videos.
@Artifexian guess youll just have to do them all over again
That little island of rainforest better survive! it'll have organisms found nowhere else on the planet!!!
Always love seeing these, they're super useful. Thank you for another video
I think you should keep more of what you consider imperfections in the climate zones. Earth has so many weird geological quirks that just look like a speck on a map but are actually 100s or 1000s of kilometers of biome that seems out of place.
This video is a tropical delight!
You're one of my favorite UA-camrs!!!!!!!
I love your videos
Canada my favorite continent
Favourite climate
Having a crescent shaped band of monsoon against ONLY the southern coast might make sense and make for good world building
Mediterranean/oceanic climates next pls 👉👈 I know you said they’re not gonna be common but they’re my favorites!
I'm doing the arid climates next but then I'll move onto the temperate ones.
Interesting part of the geography is that there isnt really a warm global south. All the rainforest only really extend upwards/northwards.
I think rivers would probably expend the tropical rainforest/monsoon forest biom to some degree.
Now...Some high fantasy ideas for them...
Now, the tropical rain forest of the Eastern Erzi mountain would be a society of tropical sea-farrers merchants and agriculturalists. Their main food crop would be sweet potatoes and rice, as well as multiple kinds of vegetables. Their main "cash crops" would be cumin, citruses, tea and cotton, their particular kind being a breed with longer staple fibers of a green color. Their cuisine is spicy, and they travel south quite a lot. They trade with the Picard tundra dwellers in exchange for dyes. Coconut play a large part of their diet. Their main proteine consist of fish, although very little of it. Those in the monsoon forest are the greatest cultivators of the green cotton.
The more in-land and near the island groups are hunter-cultivators, their diet mostly consisting of sweet potatoes, rice and coconut, in a mild-flavor profile, while most proteins consist of fresh-water fish (mostly because of the merpeople), but those who live on the tropical Island eat a lot more fish, something allowed by the lush coral reefs followed by equally lush kelp forests further south. Sea grapes are a popular treat there. Blood berries are the main fruit in this region outside of coconuts.
The tropics of Picard are home to another group, this time more gatherer-farmers, in the most rich region of bio-diversity, especially of birds. This lush land does offer them some forms of cotton, but a more primitive, wilder variety. However, this doesn't stop them, with good access to trade and different dyes, to be master weavers. A more recent colonisation event from people of the South, did create a market for another trade good: slaves. The large diversity of fruit their habitat provide also allow them to trade for better cottons, by selling of fruits. Their cottons, as well as those of South-East Erzi, are imported down to even tundra, were the various peoples have created from these imported goods elaborate traditions of wall tapistries, to decorate and insulate their tents and barracks.
The peoples of the savannahs there have an even more elaborate tradition of eggshell bead work, creating jewlery of exquisit complexity. They developped the art of turning eggshells into beads, some of which can be incredibly small and delicate.
The merpeople of the tropics specialise in pearl, sea-shell and amber jewlery, with emphasis on the beauty of the material itself, with stringing being the only modification brought on to it.
Degra, with it's tropical forests and peninsula, would also share between humans and merpeople. The mountains insure a high degree of bio-diversity, with the main fruits being coconuts, guava, plums and water berries, while the main grains would be rice. With the entirity of the continent isolated and located within the tropics, it would house a lot of species, but with smaller ranges. The humans there would mostly be nomadic, and feed on either land animals or in fresh water fish. In savannahs, some peoples of "herders-gatherers-hunters" would travel across savannah's with grazing cattle. Their main plants outside of grain would be composed of okra, plums, baobab leaves and dates, while the grains gathered are wild millet and other edible grains. Most foods are roasted, although some boiling can occure in smaller amounts because of their poor access to ceramics. The near-by merpeople are known to wear elaborate sea-bird eggshell and sea-shell beads as jewlery, with a diet mostly composed of sea cucumbers.
The tropics of Jannar are mainly rizicoles, but also cultivate millet were the climate is too dry. The region is highly productive in spices and cotton. The staple grains are short-grained rice, while their diet incorporates many fruits, mostly citrus, that are either eaten raw locally or dried and powdered as exports. The smaller islands Southwards are the main producers of such citruses. The intense heat makes the preservation of sea-food, or meat in general difficult, and thus, all populations tend to be mostly vegetarians. In savanna regions, salted figs are a common dish there. Curry leaves, galangals, sand ginger, lemongrass, cloves, nutmeg and coriander roots are shared throughout many regions. Their goods are consummed throughout the continent. The local cotton is more yellow in color, and most dyes they export are also yellow.
Wow, I'm multiple episodes behind but I have an incredibly interesting opportunity ahead of me - subduction and collision in the same place at the same time.
I would like to see how would the languages would evolve in this world, truly artistic and masterpiece
Not you clocking Amazon deforestation on that street view
i love climate zones so much!!
Does this method take in consideration the transition between the seasons? I find it weird that the two very wet zones in summer and winter are not considered to be on average very wet in between them year-round
Yes and no. This method, and all other climate-building methods I've seen, only work from two data points - summer and winter. The method is design accordingly to compensate for this. That said, it won't always to perfect. It's up to the world builder to spot any weirdness that might crop up when using only data points and correct for it based on their knowledge of how climate works on earth.
This may seem like a bug but it's a feature imo. It allows us to work with a minimal amount of maps and give us wiggle room to make creative choices.
The alternative would be to simulate climate with exoplasim.
@@Artifexian mapping by hand honestly yields better results than ExoPlaSim. If you look at its output for Earth, it doesn't take into account the east Asian monsoon(China and Korea are entirely humid year-round) or the huge warming effect ocean currents have on western Europe(Scotland and Ireland are both subarctic), not to mention that it's generally too dry on the whole(Australia(more than in reality), Madagascar, and the Caribbean are almost completely desert/steppe, much of the southern US is steppe or mediterranean, and much more of the world's continental climates are Dsx as opposed to Dfx, among other things).
40 seconds in and only the third commenter. You're getting popular.
10:00 i think you'd end up with a temprate rainforest like the pacific northwest on that far southen coast. With it transitioning to tropical rainforest further north.
It's too hot there for temperate rainforests. I think temperature rainforests occur in wet regions that average between 4-12ºC annually.
Rest in peace, Monsoon Italy, we hardly knew ye
Using this technique, you can also use it for the Cwb and Cwc climate zones. Even though they are C climate zones, these two climates are more regularly found in highland tropic areas exceeding the 18 Celsius isotherm, which are technically the more higher elevated areas. In other words: cwb and c are technically A climate zones, but at a higher elevation, or subtropical highland. NOT cwa, because Cwa are more reserved in lowland areas, and transitions to the Cfa climate zone. (to which I think Artifexian would explain in the future after deserts)
You just overlay your perception, look hor highland tropic areas exceeding the 18 Celcius isotherm, and fill in the areas. Black are still very wet zones, so there fore Cwb, and the green would be more likely drier, so Cwc.
In my world, most of my tropical continent is dry due to the area being very mountainous, so while small patches of the warm coast and warm regions are Am and Aw zones, most of the forests would be more focus on the CW zones, giving way to a mostly Savanah/ desert interior.
Quite easy and cool!
Always a pleasure to see your work, will you consider doing a reverse tectonics video. I know how my worlds land should be but i am having huge issues figuring out mountains , plates and past topography.
Confusing Canada for Africa is something I never expected to happen. They have so much in common, they're easy to confuse. 🤷 😂
I contain multitudes :P
Return the monsoon peninsula!!!
Wow, this was great, can't wait for deserts!! I wonder where the largest rainforest is on this planet?
Have you thought on doing this on a GIS software?
i think you have to factor in summer temperature for the peninsula at the first continent in the video. The winds will be from the southwesterly direction due to the heat, pulling the moisture northeastwards to the arid and semi arid areas in the upcoming video. the west African monsoon, Indian and other monsoons do a similar thing.
continent will heat up faster than nearby oceans towards the summer along-with that shallow gulf, similar to the Malay peninsula, the Andes like mountains on the east will likely channel those aforementioned SW winds northwards due to the mountains N - S orientation and the winds will be parallel to the mountains orientation. Similar to what happens in south America during the south hemisphere summer.
not a geography expert or anything just have interest in monsoons
YOOOOOOOOOOOO
YEAHHHHHH
One thing I'm rather disappointed by in worldbuilding circles is the lack of discussion of what climates should look like in situations that don't closely correspond to modern-day Earth. A polar climate is going to look very different if the planet gets enough sunlight to have only barely escaped the fate of Venus and the equator is being baked to a crisp (to some degree it will look like a tropical climate on Earth, but with more seasonality). A tropical climate is going to look different if your ice caps extend to within 20 or 30 degrees off the equator (the yearly average temperature might look like Scandinavia, but with no seasonality). Eccentricity-induced seasonality will probably give different climate patterns than tilt-induced seasonality, etc.
This might not be exactly what you’re looking for, but Serina: World of Birds by Dylan Bajda which is a spec evo project has a polar rainforest/swamp that is fully day in the summer and fully night in the winter.
@@FanFive5 I'm aware of that project, but I was more talking about theory/tutorial discussions than individual projects. It would be good, for example, to extend the Köppen system for use with fictional worlds, and for tutorial content to introduce people to the extended system.
Somebody who goes by the handle of Nyarlathotep/AncalagonTheBlack42/ForbiddenParadise64 has made an expanded Köppen system with extra categories for climates above 30C and 45C(the limit at which photosynthesis fails) year-round, as well as new temperate and "Hypercontinental" zones which reach these temperatures for only part of the year. There's also a zone for regions which fall below -100C year-round. I don't know if they've released it anywhere though.
I hope you will cover more climate zones than worldbuilding pasta
AFAIK WBP has covered every climate zone, no?
@@Artifexian true. I meant it would be cool if you for example distinguish between all the D zones and not have just one like WBB did initially (though later all zones show up). Most blogs etc. haven't really got them covered but personally, I like more detail
> "It would be like a pixel."

Fairly certain he’s using photoshop, at least for the rough outline
UA-cam didn't notify me...
Sounds like something they'd do alright smh
CANADA lol
yippee
if you finished all about cretak biomes, you should do fictional countries!
We are getting two or three more climate videos... life is good
monsoon italy 😭
goodday
Hello!
So unlike Earth all of Cretak's continents have tropical zones
I hyperventilated
CANADA????
Yup, that is a thing I said. :P
@@Artifexian 🤣🤣
if you finished all about cretak biomes, you should do fictional countries!
Countries as we think of them now are a modern construct and there's no guarantee that the people on CRETAK will organise themselves into anything that could be considered a country.
