Convectional rainfall occurs in the Equatorial region.
The Equatorial region receives a greater amount of solar radiation. When the energy of the sun heats up the earth’s surface, there is an evaporation of water, forming water vapour.
The warm air above the land surface expands and rises. The rising warm air cools and condenses, forming cumulus clouds. This results in a rainfall known as convectional rainfall.
The equatorial region receives convectional rainfall during the afternoon on a daily basis. The rainfall happens around 4 p.m, and is known as “4 o’clock rainfall”.
The abundant supply of moisture in the air, which provides high humidity, is another reason for the convectional rainfall.
Convectional rainfall is common in areas including the Tropics that receive more heat. The Amazon rainforests receive convectional rainfall.
The three important types of rainfall are:
1.Relief Rainfall
2.Convectional Rainfall
3.Frontal Rainfall
