D. Convectional rainfall
Answer» D. Convectional rainfall
Explanation: The equatorial regions are known for convectional rainfall that occurs due to the thermal convection currents caused due to the heating of ground due to insolation. In these, the warm air rises up and expands then, reaches at a cooler layer and saturates, then condenses mainly in the form of cumulus or cumulonimbus clouds. The equatorial regions receive convectional rainfall almost on a daily basis. The rainfall is of very short duration but in the form of heavy showers.
