Temperature: Insolation
Temperature of earth at point is determined by the solar heat budget at that point. Refer topic “Energy Budget” . Important concepts associated with atmospheric temperature are described below.
Insolation
Insolation is measurement of incoming solar radiation received on earth՚s surface at any specific time expressed as average irradiance in watts per square meter (W/m2) per day. It is measured by using surface element perpendicular to sun՚s rays and excludes diffuse insolation (solar ra…

Heat Transfer
Heat transfer takes place through various means like:
- Conduction: Energy transfer through solid matter from one particle to another. Energy is conducted in similar way as electricity. This process is slowed by insulation.
- Convection: It is heat energy transfer by gas or liquid movement in fluids. When air becomes warm, it rises. This action is called thermal buoyancy. As it cools, it falls. This rising and fa…
