slide13. Quick Summary—Large-scale Winds (Chapter 10):
Large-scale prevailing winds vary by latitude about every 30 degrees.
The Hadley Cell is a very persistent feature associated with rising air at the equator, sinking air at 30°, and easterly trade winds at the surface from 0–30° in each hemisphere.
The latitude zone from 30°–60° has prevailing westerly winds.
Polar latitudes have highly variable winds that tend to be easterly, with cold, high pressure systems over the poles.
This simple, zonal (west–east) wind pattern is altered by the presence of coasts, continents, and mountain ranges.<br>
