Webhow does convectional rainfall work? 1) the sun heats the ground, also heating the surrounding air 2) the warm air will rise, forming convection currents 3) as the air rises, it begins to expand and cool down. 4) condensation will take place at dew point, forming cumulonimbus clouds WebMay 29, 2024 · Convectional rainfall occurs when air gets heated & rise up producing clouds responsible for hunderstorm & lightning. Such a weather phenomenon is common in equatorial region where sun rays fall vertically over head throughout the year. Hence afternoon rain occurs almost everyday in this region.
