Convection rain
From Wikipedia, the free encyclopedia
Convection rain is a type of rain which occurs in areas that intensely heated. It is produced by strong convection currents in the atmosphere.
Strong heating of the land causes the air to rise. When the warm air rises, it expands. Being lighter than surrounding air, it becomes unstable and rises.
As the air rises, it is gradually cooled. When it is cooled below the dew point, the water vapour condenses to form clouds. The cumulus clouds develops into cumulo-nimbus clouds with immense depths of 9 to 11 km.
Convection rain is often accompanied by thunderstorms characterised by thunder and lightning. It is common in afternoon in equatorial regions, where the temperature and humidity is constantly high.
