Explanation:

Convectional Rain

This type of rain occurs when warm air rises from warm land (i.e. During a very warm summers day) The rain takes the form of thundery showers, sometimes referred to as ‘cloud bursts’. The rain will be quite heavy. This type of rain happens sometimes in an Irish summer, but every afternoon in regions near the equator.

Convectional rainfall is also associated with cumulo-nimbus clouds.  Cumulonimbus clouds are born through convection, often growing from small cumulus clouds over a hot surface.
