Ocean & Atmosphere - Coriolis Effect, Part I

In this segment, we explore the oft-misunderstood Coriolis effect, the apparent deflection of moving objects due to the rotation of the Earth beneath them. It's not true that toilets in the southern hemisphere spin in the opposite direction as toilets in the northern hemisphere and here we'll find out why.

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.

THEY BOTH LOOK LIKE THEY'RE MOVING TO THE LEFT

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

[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!

[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."

@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.

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(

Good video - thank You for simple explaining.

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

Once again - thanks for help ; )

@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

[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...

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 :/

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