I wish I could upvote this a million times. I've watched several videos on Coriolis and they only mention low pressure systems, nothing about the highs. It makes so much more sense when taking the perspective of wind direction into account! Thank you!
People, people this is a science teacher just putting online notes up for his students. No need to try and prove him wrong or tell him he is wrong. He's just doing his job and spreading his knowledge. :)
Summary: 1. Earth's (eastward) velocity is highest at equator (zero at axis/poles). 2. Things (e.g. wind) move from high to low pressure. They tend to retain their velocity (highest eastward near equator). That explains all curves/spinnings in this beautiful video,
I'll comment twice but to Blakefor8, he's talking about trying to hover over one spot, where as in the Coriolis Effect, they're talking about objects that are moving while the earth rotates. So to hover, the pilot is keeping the helicopter in the same location, right or wrong?. Also one more thing to remember is, the earth is rotating at 15 degrees per hour, so the N & S Poles would be different than the equator would be. Not to confuse people but that is why Pilots have adjustments that need to be in account when they are flying in certain directions for longer periods of time. They can't fly straight, they have to have a flight angle.
The diagram is correct. The winds in the Southern Hemisphere will curve to the left, while North of the Equator the winds will curve to the right. As these winds meet near the Equator they will be blowing in the same direction. This area is known as the Inter-Tropical Convergence Zone or ITCZ.
A common thought, but remember that both the helicopter and balloon are controlled by the atmosphere which is also rotating. A helicopter pilot will also use the Earth as a reference in flight. It is not just the solid portion of the Earth that is spinning; the at atmosphere and oceans also move. Much of the circulation of the atmosphere and oceans is caused by the Earth's rotation.
Coriolis is a lie, easily disproven by a gyro. Your confusion was you didn't think the lie was correct, and rightly so. Do some more research on gyroscopes and what they can prove, you will be surprised! No one uses it on long range shots either. ITS A LIE.
This is why Dyson spheres would tear themselves apart. Which is what made Larry Nivin Write Ringworld the way he did, and why HALO happens on a ringworld and not inside a Dyson Sphere. I think a series of rings, almost a ball, could work well too.
@SpartanEarthScience , Thisis a fine explanation of what Mr. Coriolis was thinking..I love my Celestron telescope , and have 'thrown~out' so many bologna-ass 'theories" some folks come up with trying to understand and explain to someone else how the mechanics of this actually affects things. I've had the Telescopic Instrument from when I spent the $1200.00 for the thing back in 1994. Keeping it real. The planet Jupiter is the perfect example of the Coriolis Effect. Our planet Earth is the example we all have to contend with.Thank-you for this video :)-Foxx. . =^.^=
Left or right? Rather use clockwise or counter clockwise. This way you don't have to consider "looking from the direction of the wind", or turn things upside down to see it....
Thank you so much for these videos. I do not know where in new york you are from, but you certainly have helped me to further my understanding for earth science and i am doing better on practice tests.
Concept of Coriolis effect is a very good idea but everything in nature do not occur as per this effect. Physical features of practical earth affects flow pattern of air and water on global ocean & atmosphere.
Yes, yes. I agree. The Coriolis effect is not the only cause of processes in our oceans and atmosphere. But it does cause some major characteristics of our weather and ocean circulation.
The Coriolis effect is only due to the latitudes, isn't? So if one were to bomb a city on equator from another on equator, one need consider only the actually distance over land. Is it so?
Nice explenation, im refreshing my ATPL knowledge and this is a great help! I do have a question though, do you have a video about the ITCZ? I might have missed it on your channel, but you have a great way of explaining!
If pressure at 30 degree north is lower than that at 60 degree N then how come the wind blows away from the 30 degree N to 60 degree N. Cause this seems to contradict with the fact that the wind blows from the 30 degree N ( Higher pressure) towards the equator ( lower pressure)
You are right. All objects move from higher to lower pressure. 60 degree N wind, moving towards equator will have lower original eastward component and move towards west while approaching lower latitudes. I find right and left definition (in place of east and west) very confusing!
Rather than say the wind is curving to the right or left, why not just say that the wind curves either in the direction of the spin of the earth (eastward) or opposite the direction of the spin of the earth (westward). Left or right is relative to your perspective, but the spins of the earth is a constant. Also, how is it that the Coriolis effect causes wind to curve westward (clockwise) in the tropical storm zone of the N. Hemisphere, yet hurricanes spin counterclockwise in the Northern Hemisphere.
Douglas, Great questions. Using left or right is easier for my high school students to use so they don't have to think of the added information about which way the Earth is spinning. It also doesn't work, using the "spin of the Earth" method. Imagine air flowing South in the Northern Hemisphere; it will appear to curve to the West (opposite the Earth's rotation) but air traveling North will appear to curve to the East (with the Earth's rotation). Right or left are relative to your position, so I try to emphasize that; it is a very important point. To answer your question about hurricane (and other low pressure systems) rotation see th-cam.com/video/Un2bMX2RnXE/w-d-xo.html
SpartanEarthScience But the constant in wind direction is the spin of the earth whether the air is flowing North or South and curves to the east or west. East and West are actually the same as "with spin" or "opposite spin" of earth. As you point out, air flowing North appears to curve Eastward (toward spin of the earth) and air flowing southward in N. Hemisphere, appears to spin Westward or opposite spin of the earth. Both of these effects are due to Coriolis effect. When air (or any object) flows from a higher speed latitude to a lower speed latitude, the air will appear to flow with the spin of the earth. If air flows from a lower speed latitude to a higher speed latitude, the air will appear to flow opposite the spin of the earth. That general principle will work in the Northern or Southern Hemisphere.
Unfortunately, Spartanearthscience, Has just outlined the problem with our education system. THERE is not enough time, with so few teachers, to fully explain complex thought problems; THEREFORE we must take shortcuts just to get the future factory workers to PASS the class so that the teachers and school systems can maintain their FUNDING ...... because life is all about the money now isn't it !?!?!? WE CAN"T AFFORD To take time truly helping these kids understand that angular momentum and conservation of energy are some of the OTHER concepts that will help to clarify the Coriolis effect. Now instead of just complaining I will suggest showing slow motion videos of Skaters doing spins with arms out and then pulling the arms in to speed up, If your School has a swimming pool you can get inner tubes for the students to lay across..... spin them a little then tell them to pull their arms and legs in - it will be an obvious and very personal, REAL, physical ExPERIENCE of the Coriolis effect.
@@SpartanEarthScience I mean, moving from east to west can also have coriolis force phenomenon, but it's not explained by this model, objects moving at the same latitude are similar as moving in a circle, but why there are coriolis force phenomenon, I think you have to think about gravity. Gravity is a very important factor, but it is ignored by many people, I think they are wrong, can only explain formally, not fully understood, coriolis force is not equal to geostrophic force.
@@SpartanEarthScience I have a model to think about it. Imagine a ball of yarn that diverges in the center. When it spins fast enough, the ball becomes flat, simulating the motion of a river or atmosphere on its surface. Coriolis can only explain part of it.The binding force from the center is deflecting the motion.
SpartanEarthScience suggestion : gather your thoughts and then do it , you have jupiter but your mercury keeps trying to show he is citius altius fortius , at getting to the conclusion , like a zealous but young genius . and dont you dare hate on me , i really wish well...
Coriolis effect is very selective. It doesn't apply to airplanes. Oh yeah, and when a sniper shoots across the equator, the Coriolis effect is negligible. By the way, earth is flat and does not move.
Bahahaha, who comes up with this nonsense. I guess pitchers must pay attention which direction theyre facing. With this new information i cant wait to see how my golf game improves. lol Im only going to go bowling in alleys that face north so i can get more hook. Bahahahaha.
....back up YOUR ridiculous theories! If anyone would like to see just how crazy and ridiculous some of these people are, please check out a personal favourite of mine, Lord Steven Christ, and make your own mind up. I guarantee it will give you a good laugh too! check it out, you'll be glad you did, it's very enlightening from a psychological study point of view! Lol :o)
Thanks for posting the video but could you tell me why the winds are flowing the same direction (at 4:20) aren't they supposed to go in the opposite direction? Thanks :)
Newton's 1st law says an object in motion stays in motion, so just saying that objects curve because the earth is spinning is inaccurate because the earth spins everywhere so it would seem to cancel out in your force equation. However, the precise way to convey the effect it is that the earth spins at different velocities depending on an observer's relation to the poles. The velocity vector of an object at the equator is greater than an object at the poles. An object like a bullet retains the velocity vector from its origin as it moves through space, and since the origin velocity vector is different than its destination velocity vector (either northward/southward trajectory), it curves from the observer's perspective.
Your first point is accurate; the Coriolis effect is an _apparent_ curve. I'm confused about what is canceling out and what force equation you are referring to. There is no need to bring up velocity vectors, either original or the destination to explain the Coriolis effect.
You are a damn good teacher. Can you explain in a video lecture about Jet Streams and the Indian Monsoon?How does the Anticyclonic Tibetan Plateau created monsoonal condtions, and Why do jet streams move the way they move? Pretty pleeease???
+SpartanEarthScience thanks for the reply. I found a good lecture on the Jet Streams and the Indian, west Asian and Australian south west monsoon. very well explained. thermal induction is easy, but Jet Streams were a tough game till now. all in all, hats off to TH-cam educators :-)
SpartanEarthScience - so the term “entropy” was no used, but you discuss the movement of high pressure moving to low pressure. That is entropy, is it not?
"You've gotta be the wind". Came here for science, left with a zen lesson. Very good!

Thank you so much, I finally understand the whole concept of the Equatic low pressure winds!!!
Perfect lesson to clear the directional doubts.

That is wrong. The earth does not spin, it is stationary.
True North Publisher Yes. And don't forget about the part where we didn't land on the Moon.
What an amazing video. This is my first year teaching ES. This video answered all my points of confusion in just a few minutes.

You are right. All objects move from higher to lower pressure. 60 degree N wind, moving towards equator will have lower original eastward component and move towards west while approaching lower latitudes.
I find right and left definition (in place of east and west) very confusing!
So meaning the earth rotation causes the coriolis effect and the coriolis effect causes the global wind to move in a curve way??
Yes
explained very clearly thanks!

Why not say clockwise or anticlockwise?
And when do you give the physical explanation?
1:07+
why is the south pole(WET SUF) curved to the left?
That's the way it is.
Thank you so much! ECOLOGY Test tomorrow :)
Great explanation!!thanks a lot!!
Question ：how do you explain when river or air flow from west to the east ？
Rivers flow downhill and are not affected by the Earth’s rotation.
Air moves (wind) from areas of higher air pressure to areas of lower air pressure.

incomplete explanation
Curve to right! Curve to left! Everybody move your air! Blow blow blow blow blow blow blow blow blow blow blow blow blow blow blow blow blow blow...
u better used clock wise and anti clock wise so that u won't be needing to explain again and again..
in easy way

I like this video a lot, but I DO NOT LIKE MY SCIENCE ASSIGNMENT IN SCHOOL
I love u
a genius is whom is able to explain hard concept in a very easy way. u'r a genius tks indeed :-)
why is the wind APPEAR to be moving to a certain direction when it is? You are confusing me!!
doppler radars and sattelites their use are just to predict the directions but not to avoid the formation of cyclones
Now I have no confusion of that right and left

So your saying the law of entropy is overridden by an “apparent deviation”, aka a “not actual deviation”?
No. I'm not saying that at all. Not sure where you got that from. Entropy, thermodynamics; not mentioned in this video.
SpartanEarthScience - so the term “entropy” was no used, but you discuss the movement of high pressure moving to low pressure. That is entropy, is it not?
