Chapter 8: Air Pressure and Winds

Blame it on the Coriolis






The Earth rotates, and this movement affects direction of atmospheric circulation, the most essential effect being expressed as an outward deflecting force. Coriolis, the deflective force, in the absence of other forces deflects moving objects by hemisphere, the right being north and left in the south. Winds travelling from the North Pole then become easterlies as they are deflected right, and as a whole, Coriolis plays an important role in deciding general patterns of atmospheric circulation.
