Ocean & Atmosphere - Coriolis Effect, Part I

[divantha2]

Very Clear!!! Thanx for the video!!!

[dresdnhope]

You make it sound as if the coriolis effect just happens when objects aren't moving as fast eastward as the earth surface, so the object moves westward. If it's not moving as fast eastward, that's actually a westward velocity relative to the earth, which would pull the object to the right (northward).

And you glossed over case where the effect INCREASES the velocity in the direction of the earth's rotation (South to North in N hemisphere."

[WeAreChuckNorris]

so... if I throw a ball from the south to the north, the ball will shift to the left and if I throw it from the north to the south, the ball will shift to the right.

Logicaly that means that if I throw a ball from east to west, the ball will travel more and faster, and if I throw the ball from west to east it will travel slower and not as much.

The earth goes clockwise, the clip has been flipped when recorded.. :o(

[elfdalmatae]

Good video - thank You for simple explaining.

Got my officer's exam tomorrow (merchant navy) - meteorology subject, that is.

Once again - thanks for help ; )

I understand most of it but I don't get the bottom 2 diagrams at 9:30. Why when the cloud is moving northwards in the Northern hemisphere does it still appear to be moving to the right? It makes sense in my head that it would be going to the left in that situation. Sorry if this makes no sense but I need to understand this :/

[Freedomfoe07]

THIS HELPED!!! Thankyou!!! Now I can do my speech :D

[Boxxxed]

Why is there a greater coriolis effect when the velocity of moving object is greater. If it takes less time for the object to move then there is a greater ratio of object speed to earth rotation speed and thus the rotation would have less effect on the displacement of the moving object. If it takes 0.00001 seconds for an object to move from A-B the slow rotation of the earth should have minimal effect? If it takes 12 hours for the object to move it would be 180 degrees long from its destination.

[Boxxxed]

I would post a site with good animations but I can't post any links

[marrrmar1]

THEY BOTH LOOK LIKE THEY'RE MOVING TO THE LEFT

WHY HAS NOBODY EXPLAINED THIS?!?!?!?!?

[lexmark666]

@marrrmar1 - If you were in the Northern hemisphere facing South, then the cloud would look as if it was moving to the right and vice versa.

I think that's what he meant. I'm trying to explain this to myself as well as you.

[seanmac1990]

@marrrmar1 The word Left is relative to the direction your facing.

[Likeafoxow]

@marrrmar1 imagine standing in either the northern or southern hemispheres and then watching how the clouds move. if you stand in the northern, the cloud appears to be going south towards the west (right). if you are in the southern, the cloud appears to be moving north towards the west (left). you have to try to imagine standing on the earth while youre watching these clouds...

[cashFNG]

@marrrmar1 if you viewed from above the earth then the you'll see the cloud move right. and if you viewed from below the earth then you would see the movement left. Hence North/ Southern Hemiphere

[ramanchahal86]

@marrrmar1

Look at the direction from the cloud's point of view, NOT your own. For the cloud in the northern hemisphere, its moving to ITS right.

For the one in the southern hemisphere, it's moving to ITS left.

Hope this helps.

[SooRandom01]

You are my hero ... Thank you so much

[Johannady]

i am not sure.. can you tell me if i am right?

it's like if you draw a clockwise swirl.. and you are standing up on the north..

it will look clockwise.. and if you are on the southern hemisphere you are upside down..

but you don't feel like you are because of gravity.. so it looks like it is going counter clockwise..

[ineverfakejumps]

If a cloud was moving south while in the southern hemisphere, wouldn't the Coriolis effect still deflect it to the right? Why left?

[Sn0wFreak]

@ineverfakejumps thats what i am thinking

[Flexelek]

Really nice vid, well done mate. Gonna have my state final exam on the 9th, in geography. Atmospheric studies were like 4 years back, this really refreshed my memory. The thing the other videos miss is the latitude speed component. Moevement of clouds going towards the equator is easy to understand, but going towards the pole is a bit different, and the starting velocity is the key.

Again, big thumbs up. Keep em coming :)

[g7019487]

this guy is a hero, cheers man.

[rgsgt]

boom diggidy. now i'm ready  to take my midterm

[domyaska]

thanks a lot for sharing this explanation!

[ShannonMarie0121]

i wish you were my science teacher. this video was very helpful

[scxq28]

The eastward component of an object at the equator is faster than anything north or south. So as the cloud moves north, it moves east faster than the Earth spinning beneath it.

[ZiePe]

Well, although this is better than any other explanations on youtube, it must be very simplyfied: I get why the objects moving towards the equator appear to drift to the right in the north and to the east in tje south but shouldnt it be the opposite (left-north/right south) when objects are moving away from the equator? Plus, I dont get why objects moving on the east-west axis are effected.

[jungshin87]

ur the best

[clovericecream]

THANK YOU! Gosh, I have been so very confused about the way that this was initially explained to me. Thank you, thank you, thank you!

[christianaxelsen]

Thank you for this video. It helped my exam...

[jorgonlor]

This video is wrong, like most of thw youtube video trying to explain coriolis effect. If what this man is telling us is true, the cloud would always be moving aparently in the same direction, no matters north/south direction neither north/south hemisphere, which is not the case.

[cowgal2007]

you are boring

[ESJBOSS]

This movie and its explanation for Coriolis is actually misleading and WRONG. It does not explain why there is a deflection when things move East or West. The actual deflection cannot be explained by the earth moving below the object (it is a factor of two off if we calculate it when an object moves North or South).

[AnnabelleLeeII]

Oh? S how would you explain the coriolis effect?

[ESJBOSS]

To be exact, you will have to bring into account concept such as angular momentum, gravity, centripetal acceleration and the like. Without them you cannot explain how an object fired E or W gets deflected.

[thegoldenbluej]

very helpful, I didn't understand the coriolis effect before watching this vid and I had an exam the next day. This really helped!

[wwtsniper]

Thank you very much. Your explanation finally made me understand the coriolis effect fully. I always understood clouds turning to the right in the northern hemisphere when moving from the equator to the pole but not the other way around.

Because you mentioned the speeds at different latitudes, and thus the initial speed the cloud gets, the difference in speed finally hit home although not very clearly explained in the video. But that's just a tip.

Thanks a million though. :D

[Baalsaack]

At the end: why does the cloud moving north look like moving to the left in the South hem. but in the North hem. it looks like moving to the right? He says it should be apparent, but it's not to me. The Earth is moving in the same direction, so shouldn't all the object moving in North-South line look like moving in the left dirction?

[jerkoon]

I think i finally figured it out thanks to this vid!

I'll try to explain in my words:

At the equator, the speed (rotation) of the ground is the fastest. So if a cloud moves toward the equator (N or S hemisph.) the ground beneath it at its destination has moved faster than at it's starting point. So although the cloud made a straight line, the ground at its destination moved away. So it appears to make a curve to the west. When it moves away from the equator, it makes a curve to the east...

[AnnabelleLeeII]

instead of a cloud, pretend it's a bird flying in the Northern hemesphere. As the earth spins beneath the bird, the bird's path is deflected TO THE BIRD'S right.

Yeah, I didn't understand that either until I saw this video.

[teditodorova]

OMG!!!
