What is the coreolis effect?

Answer 1

It is an apparent force caused by the rotation of the earth. A parcel of air moving from the poles toward the Equator will appear to curve to the right. This is because the earth has moved under the parcel while it is in transit. The Coriolis parameter must be included in algorithms used to calculate air mass movement to correct for this effect.

Answer 2

The Coriolis effect is the effect that the earth's uneven rotational speed has on long-lasting and large vortexes.

Which means if you have a bowl filled with undisturbed water that has a small hole in it, it will drain clockwise in the southern hemisphere and counter clockwise in the north. The Coriolis effect does NOT affect the rotation of your drains or your toilet. Those vortexes are too small and don't last long enough.

Answer 3

Larry T has it pretty well right, the time scale for motion should be longer than a day, Coriolis impacts all motions, and goes a siin(latitude) so you need be off the equatorial regiime to notice its effects

Answer 4

In a rotating environment, an object travelling essentially parallel to the axis of rotation appears to be deflected.

Answer 5

This effect is why storm systems tend to move in particular directions

Answer 6

thats where water swirls down the drain in your sink. it's caused by the rotation of the earth.
