Convectional rains are typical of equatorial areas. Convectional rainfall occurs when the sun heats the ground, causing the air above to become warm and rise. As the warm air rises, it cools and condenses, forming clouds. The clouds continue to grow until they can no longer hold the water droplets, which then fall as rain. In equatorial areas, where the sun's rays are most intense, the heating and rising of warm air is more common, leading to frequent and heavy convectional rainfall.
