Solar Radiation, Heat Balance and Temperature
Insolation is the energy received by the earth as the incoming solar radiation. The amount of solar radiation received at a place during a particular time is determined by the factors like:
The rotation of earth on its axis
The angle of inclination of the Sunrays
The length of the day
The transparency of the atmosphere
The configuration of land in terms of its aspects
The earth radiates back the heat received through insolation through the processes of
The earth maintains a balance between the incoming solar heat and the outgoing terrestrial radiation, which is known as the heat budget of the earth. In the absence of this, the earth would have been excessively warmer or excessively cooler.
Temperature is the degree of hotness and coldness of anything. There are various factors which affect the temperature of a place like:
The latitude of a place
The altitude of a place
Distance from the sea, the air mass circulation
The presence of warm and cold ocean currents
The local aspects
The distribution of temperature is represented by the isotherms.
Inversion of temperature is the deviation from the normal pattern where the temperature decreases with the increasing height.
