The type of rainfall depends on what causes the air to rise.
Convectional rain
Usually in summer the ground gets heated since early morning. The air which is near to the hot
ground also gets heated.This hot air then rises, cools down and forms clouds. By early afternoon
thick dark clouds are formed.
Heavy rains occur and last for a short period of time only, one or two hours usually. After the heavy
rains, the sky once again becomes clear.
Sometimes these rains are accompanied by thunder and lightning.This is called a thunderstorm.
