What is the relationship between wind patterns, latitudes and pressure belts?
The equator is warm, air rises, creating low pressures. The poles are cold, air sinks, creating high pressures. Because of the Coriolis effect, the rising air at the equator falls back spinning to the right at roughly latitude 30 N, creating a belt of high pressures. Between the sub-tropical air masses and the polar ones, a front exists at roughly latitude 60 N. Along that front and due to the warm air climbing over the cold one, the pressure sinks, creating a belt of low pressures. Between the sub-tropical high pressure belt and the equatorial lows, the wind is coming from the east since a low sees counter-clockwise wind and a high, clockwise. This the Trade winds belt. Along the polar front, and due to the Jet Streams created by the difference in the tropopause and the Coriolis effect, a strong westerly wind taking the lows to the east, is the the so-called westerly wind belt. Between the two, the air moves, of course, clockwise, following the effect of the Coriolis and, for example,
