Question

im sorry but im new student in geography(degree),,can somebody tell me in general about INSOLATION?
thank you^^

Answer 1

Lol just google it, very simple

Answer 2

This has to do with local energy budgets.
An energy budget refers to the amount of energy entering a systerm, the amount leaving the system, & the transfer of energy within the system.
Here, it's considered as a micro-scale.

Incoming solar radiation (or insolation) is a part of the daytime energy budget, which involvers insolation, reflected solar radiation, surface absorption, sensible heat transfer, long-wave radiation, & latent heat.

Incoming solar radiations (insolation) is the main energy input & is affected by latitude, season & cloud cover.
Insolation varies with the angle of the sun & with cloud type.
E.g. with Strato-cumulus clouds when the sun is low in the sky, about 23% of the total radiation transmitted is received at the Earth's surface. When the sun is high in the sky about 40% is received. The less cloud cover there is, and/or the higher the cloud, the more radiation reaches the Earth's surface.
