Convectional rainfall occurs in the equatorial region. Convectional rainfall is a type of rainfall that is caused by the upward movement of warm air and the subsequent condensation and precipitation of moisture. In the equatorial region, the sun`s rays are more direct and intense, which leads to the rapid heating of the land and the air above it. This causes the warm air to rise and form clouds. As the warm air rises, it cools and condenses, resulting in heavy rainfall. The equatorial region is characterized by high temperatures and high levels of humidity, which are conducive to the formation of convectional rainfall. It is important to note that while convectional rainfall is most common in the equatorial region, it can also occur in other regions with similar climatic conditions.
