Why does the Coriolis effect exist?

It exists because the kinetic energy of something moving across the surface of the Earth is preserved. When an ice skater spins around her axis, and starts moving the mass of her arms and leg towards this axis, her kinetic energy will be preserved, so as a result she will be getting more rotations per second;. read more

The Coriolis Effect does exist, but I am not aware of it being USED for anything. Rotating weather systems, water down a bath drain, gyroscopic drift, will work in the opposite direction when you cross the Equator. Low pressure systems rotate anticlockwise in the North, High pressure, clockwise. read more

“ This is the complete pattern and scale of ANY Coriolis effect on the Earth. If something in the real world doesn’t match this, it can NOT be the Coriolis effect!”(3) “They say it is this effect which causes moving objects to be deflected in a clockwise direction in the northern hemisphere and anti-clockwise in the southern hemisphere; an example of which are large cyclones. read more
