Heat Budget of the Planet Earth
The entire planet does not store or release heat. It keeps its temperature constant. This is only possible if the heat absorbed from insolation equals the heat the earth loses from terrestrial radiation. 35% of solar energy is reflected back to space even before it reaches the earth’s surface when 100% of it enters the atmosphere of the planet. The quantity of reflection is referred to as the earth’s albedo. The earth or the atmosphere is not heated by this energy.
The amount of radiation reflected by the earth is known as “Albedo”.
35% of solar energy is reflected back to space even before it reaches the earth’s surface when 100% of solar energy enters the atmosphere of the planet. The remaining 65 units are absorbed, with the atmosphere absorbing 14 units and the surface of the planet absorbing 51 units. The form of radiant energy that the earth emits back is 51 units. Of these, 34 units are absorbed by the atmosphere, leaving only 17 units that are directly emitted into space. In addition to being reflected back into space, the atmosphere absorbs 48 units (14 from insolation plus 34 from terrestrial radiation). In order to balance the total of 65 units received from the sun, the total radiation returning from the earth and the atmosphere, respectively, is 17 + 48 = 65 units. This process is known as “The Heat Budget of Earth”.
Solar Radiation – Heat Balance, Transfer & Distribution of Temperature
Here we are going to discuss a Geography topic which is ” Solar Radiation – Heat Balance, Transfer & Distribution of Temperature “. This topic is a part of the general awareness of many competitive exams. This article covers the entire essence of the topic by which you get the most out of it. This article is very helpful for SSC, Banking, Railway and for other competitive exams.
