Global Patterns of Atmospheric Heat and Circulations

1. Describe global patterns of atmospheric heating and circulation. What mechanisms produce high precipitation in the tropics? What mechanisms produce high precipitation at temperate latitudes? What mechanisms produce low precipitation in the tropics?

2. Use what you know about atmospheric circulation and seasonal changes in the sun's orientation to earth to explain the highly seasonal rainfall in the tropical dry forest and tropical savanna biomes. (Hint: Why does the rainy season in these biomes come during the warmer months?)

Global Patterns of Atmospheric Heating and Circulation:

The climate is protected by circulation processes that take place at the atmosphere in the global air movement air patterns. The heat imbalance of the surface of the earth is what causes the circulation of air over the earth. The heat imbalance of the earth is regulated by the global circulation of the pressure and the winds. It is through these heating and circulation patterns that the oceanic currents are created. The warm air is less dense than the cool air. This means that it is capable of holding the moisture content termed-water vapor (Ritter, 2011).

The atmospheric circulation being the largest scale of air movement ensures that the thermal energy is well distributed on the earth surfaces. In this processes, the atmospheric air shifts at the poles of the earth. The large scale circulation processes of the earth takes place at the atmosphere creating an uneven balance in the heating of the surfaces of the earth by the rays of the sun. It is imperative to note that the atmospheric heating is higher at the equator since the rays of the sun are vertical to the ground unlike at the ...

Solution Summary

Global patterns of atmospheric heat and circulations are determined. The atmospheric circulations and seasonal changes in the sun's orientation to earth to explain the highly seasonal rainfall in the tropical dry forest and tropical savanna biomes are determined.
