Global patterns of atmospheric heating and circulation.
The patterns of atmospheric heating and circulation occur through air movement, and typically happen through convection where there is energy transfer the earth’s surface (Satoh, 2013). This process takes place because of unequal heating on the earth’s surface, which then influences precipitation patterns. Warm atmospheric air moves from low attitudes to high attitudes, while cold atmospheric air shifts from the high attitudes towards low attitudes. Heat in the atmosphere facilitates circulation, which takes place at the troposphere part of atmosphere nearest to the earth (Satoh, 2013).
High precipitation in the tropics
Sun heat affects precipitation patterns in the tropics by heating the atmosphere and the earth’s surface. After heating, there is resultant air expansion in the tropics leading to a rise in the warm air. The rising warm air meets cool air and this is accompanied by reduced water vapor. Consequently, the rising air condenses resulting in cloud formation, which then triggers rainfall and rainy weather. Furthermore, the sunrays hit the equator directly, while trade winds converge at the equator all triggering high precipitation in the tropics.
High precipitation at temperate latitudes
Temperate areas have warm summers and cool winters, and hence the weather patterns are not extreme. Dry air from the deserts at around 30° separates the tropics from the temperate region (Satoh, 2013), and in these, temperate zones warm air moving towards the polar regions meets cool air from the poles resulting to cloud formation that trigger high precipitation in the temperate latitudes.
Low precipitation in the tropics
Air temperatures affect precipitation, and warm temperatures result to more precipitation. However, insulation of ...
