The above situation happens because the large latitudinal difference is an important factor in controlling climates of different region.
Firstly, the extreme atmospheric energy supplies is contributed by the latitudinal difference because it affects the angle of the sun. In low latitude regions, the angle of sun is small and then energy they receive would be very concentrated. However, in high latitude regions, the angle is bigger and the area receiving the stroke of sunlight would be bigger, this spread the energy and so marking the difference in atmospheric energy supplies.
Secondly, the distance between the earth and the sun can also be explained by the difference in latitudes. Sunlight travels a much shorter distance in lower latitudes, causing less scattering, reflection and absorption. While in the higher latitude regions, the longer distance made the energy finally passing through the atmosphere smaller and therefore, extreme atmospheric energy supplies can be the result.
Thirdly, surface albedoes in various regions are different and so extreme atmospheric energy supplies can be a result. In regions of higher latitudes, albedo is high especially areas covered by snow and icecaps. While in lower latitudes, albedo is less significant although cloud cover also reflects much of the sunlight in the air. Therefore, the high difference in surface albedo may lead to the extreme energy supplies in atmosphere.
With the above reasons, that explains why the Tropical Rainforests in the Equatorial Regions receive a much higher atmospheric energy and a decrease of energy supplies can be found with increasing latitudes.
Extreme atmospheric energy supplies can also be attributed by the effect of ocean currents. If the region lied along the area where warm ocean currents pass through, the atmospheric energy will be higher and the opposite will happen to the areas where cold ocean currents pass through. For example, the Cold Labrador Current brings the North America a rather low temperature. And in South America, the area is under the influence of the warm Brazil Current so the temperature is milder. Therefore, the ocean currents would be another factor.
Apart from the above physical factors, our world energy supplies can also be affected by human factors. These human factors can bring a higher atmospheric temperature or a lower atmospheric temperature to the world.
Due to the overuse of CFCs, there was a hole in the ozone layer over the Antarctic. This allowed more sunlight, including the harmful ultra-violet radiation to enter the atmosphere. As a result, the atmospheric energy supplies increase as a result.
Also, because of the industrial development, there is high emission of carbon dioxide. This becomes the major cause of Global Warming which led to an increase of global temperature. This becomes another proof of modification made by human activities.
Tall and dense buildings also contributed to the increase of atmospheric energy supplies. The highrises trap heat among them and did not allow space to scatter them. This is frequently seen in developed areas like Hong Kong. Therefore, human activities can influence atmospheric energy flow.
In addition, deforestation brought tremendous effect on atmospheric energy worldwide. With fewer trees, there is more carbon dioxide in the air and carbon dioxide is one of the major greenhouse gases. As a result, with fewer trees, temperature of the earth increases and so affected the energy flow.
The increase of automobile use also enhances the greenhouse effect. Cars emit carbon monoxide and increase the city temperature. This effect is observable in city areas of various regions. This further proves that human activities can modify atmospheric energy flow.
In conclusion, the atmospheric energy supplies in different climatic regions varied a lot and sometimes contribute to extreme atmospheric energy supplies. The combined effects of physical and human influences shaped the current pattern of climatic condition where atmospheric energy flow varied.
