General atmospheric circulation:
1) At the equator, the sun heats up the Earth and the atmosphere. This causes the air to rise and low pressure is created. This area is known as the intertropical convergence zone.
2) This rising warm air moves towards 30 degrees north and south. As it moves away from the equator it cools and at degrees N/S it sinks. This creates an area of high pressure. Some of the cool air reaches the Earth's surface and eiher returns to the equator…
