Slide 1

Worldwide Pressure Belts and related Surface Winds

Slide 2

ASSOCIATED PRESSURE BELTS Rising air at the equator causes the central belt of low weight Descending air at around 30 ºN and 30º S causes the sub-tropical belt of high weight Polar high weight Mid scope low weight Sub-tropical high weight Rising air at around 60 ºN and 60º S causes a mid-scope belt of low weight Equatorial low weight Descending air at the posts causes the polar high weight ranges Sub-tropical high weight Mid scope low weight Polar high weight Q

Slide 3

ASSOCIATED SURFACE WIND PATTERNS Winds dependably blow from high weight to low weight. They are diverted in view of the Coriolis Force which come to fruition on account of the revolution of the earth. Polar high weight Mid scope low weight Sub-tropical high weight Winds in Northern Hemisphere are redirected to one side. Tropical low weight Winds in the southern half of the globe are diverted to one side. Sub-tropical high weight These wind belts move regularly. (See next segment) Mid scope low weight Polar high weight
