Solar Radiation, Heat Balance And Temperature

Question

Wired Faculty App

Describe the distribution pattern of insolation.

Solution

The distribution pattern of insolation is described below :

(1) The maximum amount of insolation is received at the equator and it goes on decreasing towards poles.

(2) Along the parallel of 45° latitude, it is only about 75% of that at the equator.

(3) Along the parallels of 66^1/2°, it is about 50% of that at the equator.

(4) At poles, it is about 40% of that at the equator.

In this way, we see that maximum amount of insolation is received at the equator and minimum at the poles.
