I was going to crack a terrible joke about hurricane eyes. I changed my mind because I feared the prospect of someone coming back with something even cornea.
lol
That was a stupid joke and you should feel bad about yourself.
Sorry eyelashed out on you like that.
***** I'll get my coat.
Keira Churchill I stole your coat
Keira Churchill LOL
2:49 Nicholas Carnot's ideal engine is not used in a car....so Carnot.
that what he said
Fuckoff
Car-NOT
It's amazing to consider that much of our history could be traced back to events that were beyond the control of human agency. Imagine what Japan would be if they were not protected by typhoons in those pivotal moments.
They'd probably be almost identical because the Mongols only asked to acknowledge the khan as supreme ruler and a tax. That or Japanese people would've been entirely wiped out if they refused.
mongolian anime!
Hard to say, some cultures, like Russia, were heavily affected, while events like the Mongol invasion China in the end just looked like another dynasty
Not much. Mongolians were good warriors, but their culture was not that invasive. All the civilizations they conquered, like China, Persia or Russia retained their cultural identities. The Mongols that conquered these lands eventually got assimilated in the native culture.
That's true. Very good point.
Quite a good explanation of the Carnot-Process, wish I had this a few months ago when I had to figure out Thermodynamics
Interesting topic, but one major request, when using non-standard units (or standard units for that sake), could you please include the standard (or non-standard…) conversion as well?

Hurricanes are fascinating but so deadly
omg
The Great Red Spot laughs at how pathetic all hurricanes on Earth are.
Laughs in Jovian
Thank you for brightening my day
Hurricanes might be similar to an ideal engine, but the ideal hurricane is one that never forms.
Whoa... Master-ception. lol
Not entirely correct, while they are destructive, and I might be bias due to chasing TCs in Australia, but they are an integral part of the water cycle, and in Australia farmers out West Depend on TC season for rain some years.
Princess Haley Praesent Interesting. Rain and storms are obviously important to farmers, but I would think the high wind of TCs would cause crop damage.
normal storms don't have the energy to make it over the Great Dividing Range with enough rain left to get water to them, plus unlike most of the world including america we have super strict building standards and a huge budget in lowering damage caused by TCs, most buildings, including my own home, are now rated to Category 4 with Category 5's being the only one we haven't built for yet but many universities get massive grants on researching that.
Princess Haley Praesent I never would have guessed that some farmers rely on cyclones. Thanks for the info ^_^
Did you chase storms as part of a research team or just for "fun"?
Excellent graphic description. Very educative
These videos are always perfect. Brilliant work, keep it up!
you are close to 1 million subscribers... much deserved channel.. thank you
outstanding presentation, especially that end, well combined
Stop scrolling down to the comments and watch the video.
+Your Master hi
SHUT OOOP
+Stephen Chen are you talking to me
I'm sorry...
hadeghe hadeghe no im talking about Your Master
Buoyancy is the key reason why jupiter's Great Red Spot is anticyclonic. On Earth cyclones are formed when gases rise up and are met with rotational spin. On Jupiter cyclones are formed when gases sink back down to the planet's metallic surface. Gases rise from the super heated core, and as they cool they sink back down. That combined with rotational motion forms the characteristic vortices.
Jupiter is a gas giant...
@@ParkerBlank the center of Jupiter is most likely a metallic core - gasses like hydrogen and helium compressed so tightly that they form a metallic structure.
Hurricane Patricia 2015 had max sustained winds of 215 mph in the East Pacific which is insane
I was thinking the same thing when he was talking about the theoretical limits. This is bananas
215mph is hilarious. The first time one of those hits a city it's going to be a global wake up call.
@@aluisious If that were the case Katrina would have been a wake up call, because like he said in the video at a certain level of destruction you really cant get much worse. Truth is too many people shove their head in the sand and want to live blissfully ignorant lives.
Thank you so much!! U explained it better and clearer than anybody else.
Actually the circumstance of the concept within the theory is really easy to understand if you divide the speed of the circumference with the negative factors related to torrential force plus a few other factors you begin to understand that it is nature. Now with the aforementioned concerned.,.hold on a minute.
Thank you this was very helpful and informative 👍👍
And since this video we’ve had Harvey, Irma, Maria, Michael, Florence, Dorian, Laura, Eta, Ida, Fiona, and Ian. Not to mention the many typhoons.
Came here out of curiosity thanks to recent events. Harvey and now Irma is showing just how powerful these stotms can be and its frightening. I hope things won't get any worse in the future.
Irma. Ike, Ian, the I's have it
@@daverobinson6110 and Ida
María entered the chat
I am here from the future, it got worse and shows no signs of slowing.
That was awesome. more metrology please 😀🙌🙌
What did the hurricane say to the island?
*iv'e got my eye on you*
I stole it for my Facebook. It's bad timing... but I think it will hit
Great explanation, thanks
This would be such a perfect way to demonstrate a simple rankine cycle to thermo students in college.
Would be lovely if you'd consistently support metric units throughout the video. Its kind of frustrating for those not using the imperial system on a daily basis and having to wonder how much pounds and miles per hour are :P. Otherwise great video, many thanks!
Its almost like you could learn or study to gain a general idea if you’re interested in continuing to watch American videos. Its like watching a Chinese video and whining about them not speaking english. Its more entitled wokest bs. Get tf over yourself. The vid was mad for Americans anyway
+
Beautiful explanation
Louisianan here. I’ve been through many a hurricane. The only ones we actually evacuated for Katrina and Gustav. Ida was labeled as really bad, but we stayed and only had superficial damage
powerful and very strong when it travels to a distance in any direction on how the cyclone moves on to one city to another and it can be creative in different forms on the system being a major priorty in the world now
It's an anticyclone, a high pressure cyclonic storm which goes in the opposite direction from the rotation of a fluid, in this case air.
And by the way please add challenging questions every video its fun
so interesting omg
how could i live without this information?!
hi bis
Wow such a great explanation
What's with all the Imperial units?
Cuz murica...
(Sigh)
you never know, it could be one of the other many countries still rocking imperial!
- Liberia
-Burma
+razzed1310 ...nah
Burma is not a country. Myanmar is. Unless you ask the US Government.
+Christopher Pilcher the US isn't a country, United States of America is
That's a lot of variety of physics departments to explain one phenomenon.
MIND BLOWN !!
It's 2022 just before Ian makes landfall and I know this is reviving an old video but... Instead of categorizing hurricanes, typhoons, cyclones, tornadoes by just wind speed and the resulting amount of destruction, we need to start adding in the rate at which things are destroyed or redistributed. The faster buildings and foliage destroyed and the rate of convection occurs should be the overall determinate for these purported "megastorms"
Fascinating
i like this video it very educational, especially the kamikaze
Ok usually I can understand your video in just one go, but this video I had to rewind a couple times to get the hang of it.
"Then the Mongols died in a tornado."
well maybe a typhoon hit then a tornado
2:31 that’s Hurricane Isabel. I remember that one!
amazing!
correction ... typhoons hold the torch if any storms do ... the strongest storm on record with the lowest pressure is still Super Typhoon Tip back in 1979. then one of the most potent typhoons also was Super Typhoon haiyan (also called super typhoon yolanda in phillipines) back in 2013. also asias' "hurricane season" typhoon season often see 2x more storms than the US season. the atlantic average is 10.1 storms per year ... the western pacific avg 26 typhoons a year. another fun fact : a hurricane low pressure at the surface spins counter-clockwise and the outflow at the top of the storm spins clockwise. thats why you see the main storm spinning counter clockwise but you still see some clouds moving in an unnatural looking way clockwise
carnot cycle (almost) in real life... wow... i definitely learned something today...
Perhaps The Giant Red Spot is between two wind belts causing it's opposite rotation
this video was particularly good
all those early ones,go to Rio...they are giving medals
HAAAA an olympics joke ...
you couldn't get any less irrelevant.
The Carnot engine explanation was kinda confusing, but Google saved the day once again.
For the answer in the challenging question the answer is this : The G.R.S(Great Red Spot) is an anticyclone because a cylcone has low atmospheric pressure but the anti cyclone has high atmospheric pressure.Its high pressure because of jupiters temperature, jupiters temparature is -145Degrees(-261 F) at your video you said at the carnoa engine if "if pressure is high heat is low"(not exactly u said) so all that in short means the G.R.S(Great Red Spot) is an anticyclone
1996 tropical cyclone, Olivia. This was a category 4 hurricane that passed by Barrow Island, Australia. This storm had wind speeds of 254 mph
Not sustained winds, but gusts
Oh, so that's where Lamborghini got their names from. LOL!
Superb
Explain the Arctic and Antarctic Vortices, what keeps them going?
please use international units too. cool vids :)
Super Superb!! Super Superb!! Super Superb!!
Thanks.
It may be similar, but how bout a video on Tornados, and maybe why tornado Alley sees more than its fair share.
I would guess Jupiter's Great Red Spot rotates counter-clockwise, despite being in the southern hemisphere and Jupiter rotating west-east, is more due to the two powerful atmospheric streams in moving in opposite directions at the Spot's latitude.

Looks like the beginning of the video took some inspiration from Civ with those tiles. Can bet Gandhi was in the Atomic era in 1274
Yes, as the animator I can tell you I am having a small civ5 addiction problem right now.
1:50
why is a wind travelling north also moving east along earth's equator? is it simply being dragged by earth's rotation?
When I was in first grade in Hickory Mississippi we were learning about storm formation, we talked about Tropical Storm Katrina, at the time I didn't think anything of it.
to be honest it was first predicted to head towards the florida panhandle
And you don't think now, you haven't learned anything yet..huh dummy?
I could be wrong - the pressure on Jupiter is great enough to make the the spin move more like water. then how it shows on Earth. Maybe something else with the poles.
interesting video!
Omg I just finished a project on hurucan a while back, this vid would have helped, I mean I did get an A so, doesn't matter
I guess you just gave massive spoilers on netflix's Marco Polo
The first season was quite good, the second is just dissapointing.
=/
Could someone please name the video containing the answer to the challenge question?
It doesn't seem to exist
@Ozone Haha, first time anyone has ever said that to me. Bout time!
Kublai khan was one of my predecessors
Hurricane Isaias! 💪🏽 here from Florida
The GRS spins counter-clockwise because it is being "pushed" west by an air current north of it, and east by an air current south of it.
*dat cringe when you go back and see that it says to email it* prob wrong anyway
Thanks
Since there is phase change of vapour to liquid involved, isn't this a modified tanline cycle than a Carnot cycle?

We studied this subject and its details for a month at school, when it could be explained in just 6 minutes.
Your teacher should have done more teaching instead of learning you.
+Adam Eronen Piper My thoughts exactly.
Adam, are you trying to make fun of Chris with that sentence? His use of "learned" (pronounced "learn - ed" in 2 syllables) is a proper use of the word meaning "well informed" or "taught." Like in the phrase, "he is a learned scholar." Your use of "learning" is either bad use of grammar, or an attempt at making fun of Chris? If it is the latter, then you've just shown your lack of understanding.
A tree falls in the forest...
Adam Eronen Piper ...and you were around to hear it.
How did people (especially native Americans) know that hurricanes were spiral shaped if they didn't have sattellites to see them move?
Please explain, I can't find the answer on Google.

Haven't been in a hurricane, but if the eye will pass over you, before him, the wind will be in one direction, after the pass will be in the contrary.... the most advanced indigeneous cultures had pretty sensible observers (scientists?), they have pretty good knowlegde of the stars; for me it isn't impressive they notice that!
People noticed that as a hurricane traveled through mainland, fallen trees would point in the direction the wind had pushed them. Hurricanes that traveled to the north through land were easiest to identify. Fallen trees to the West of a hurricane's strongest winds always pointed South. Fallen trees to the East always pointed North. Fallen trees within the path of the strongest winds immediately to its West pointed West because the left side of the hurricane was more impactful there and immediately did more damage, whereas trees immediately to the East pointed East, as the backside of the hurricane packed more of a punch on this side.
It looked something like this. Imagine that a hurricane has traveled North through the land and you notice, after looking at the damage, this pattern of fallen trees:
T = Standing Tree
v = Fallen, Pointing South
> = Fallen, Pointing East
< = Fallen, Pointing West
^ = Fallen, Pointing North
/ = Fallen, Pointing Southwest
\ = Fallen, Pointing Northwest
Hurricane's Path Northward

They noticed that the trees could only fall in this consistent pattern if a large, swirling eddy of wind passed through, rather than a straight line wind. More immediately, though, those who experienced the center of a hurricane noticed that the winds would blow from one direction, stop as the eye passed over, and then come just as fiercely from the opposite direction. They deduced that the eye was the center of a tempest and that the storm system in the strongest part of the hurricane orbited it. Fascinating how they were able to figure that out without satellites to aid them. Very smart and observant cultures, indeed.
tornadoes???
Adding another category is a stupid idea. At some point we'll reach CAT 7 or 8, and a CAT 5 is suddenly not so scary anymore, right?
does anyone else find that its easier to view maps when the landmass is shown in a lighter colour and the water in a darker colour unlike the map used in this video??
Maybe this is how dark energy creates galaxies. Moving dark energy meets another dark energy then condensation of atoms happens and then it starts spinning like all spiral galaxies. What we call a black hole is actually the Eye of the storm. It is the critical component of a perfect galactic engine
Yeah ok lmao 😂 🤦♂️
I like the music.
Nice
I wanna know the physics of biology. How do my body parts work the way they do, from a physics perspective?

Hurricane typically get over 200-300 miles across and some get over 800-1000+ unlike what the video says. Food for thought.
This in my recommend feed now that my whole town curb stomped by hurricane Ian
Very awesome explanation but also difficult for my smooth brain to understand.
is it because the inside in going that way, just faster so it acts like a gear?
The emperor was using very huge Ransengan for sure.

Episode idea: If we look into every square inch of the sky, is there a star there?
I’ve always wondered, if we could see every star, would the night sky be white?

Hey I saw you on one of the biologist I follow on Instagram, were you in Peru? I'm pretty sure I recognize the parrot from the lodge.
There was a cyclone in Australia that destroyed the northern city of Darwin in the 70's.its name was Cyclone Tracy and some of the estimates of wind speed where astronomical 400 km per hour.An eye witness said that telegraph poles that where made of railway lines where twisted like a cork screw
I think the windspeed is in gusts is it?
Those were likely gusts. Still obviously an insanely strong storm, probably one of the strongest in history.
