Where do the westerlies occur?

What are the 4 types of winds?

The Four Major Wind Systems and Wind Belts: The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone. These are also wind belts. There are three other types of wind belts, also.
