explain all the pressure belts and wind system .Thanks
All air movements have their roots in pressure differentials in the atmosphere, called pressure gradients . Systematic differences in the Earth's land temperature affect air pressure, and significant patterns of pressure that persist over time are called pressure belts, or wind belts. On the earth’s surface, there are seven pressure belts. They are the Equatorial Low, the two Subtropical highs, the two Sub polar lows, and the two Polar highs.
Thank you.
