Describe the Global movement of air?

This movement is done so in a pattern. Its all driven by the Equator, the hottest part of Earth. The air there rises, leading to low pressure and rainfall. When the air had reached the atmosphere, it can't go further so it goes North or South. They will soon get cold and will therefore fall to create high pressure and dry conditions at 30 degrees North or South. Large cells of air are created by this. The air will then rise again at 60 degrees North/South and fall 90 degrees North/South This creates wind and areas of high rainfall [Tropical Rainforests] and low rainfall [Deserts]
