Pressure Belts and Winds

Pressure Belts and Winds
Atmospheric pressure at sea level MORE
Atmospheric pressure on the mountains LESS

when Temperature is LOW Pressure is HIGH.

There are three pressure belts:
1. Equatorial Low Pressure Belt (Doldrums)
2. Tropical High Pressure Belt (Horse Latitudes)
[Here, the pressure is high although high temperature because here pressure depend on the rotation and movement of air]
3. Sub Polar Low Pressure Belt


5° N to 5° S
Doldrums
5° to 30° N and S
Trade Winds
30° to 40° N and S
Horse Latitudes
35° to 60° N and S
Westerlies
60° to 65° N and S
Sub Polar Low Pressure Belt
