The equator receives maximum amount of heat from the sun because of its position in relation to the sun. The poles receive minimum amount of sunlight because the sun's rays fall at a slanting angle and create a high pressure region. The air between the latitudes of 30° and 60° are warmer compared to the air at the poles. Warm air at the equator rises and creates a low pressure near the earth's surface. This void is filled by the cold and dense air from the poles. This uneven heating of the equator and the poles lead to a difference in the air temperature, which is responsible for the generation of wind currents.
