WebAug 18, 2024 · 1. Consider the following explanation of convectional rainfall given in a VII grade textbook. When air comes in contact with the hot surface of the earth, it gets heated, becomes light and rises in the form of air current. After the warm air current reaches the upper layers of the atmosphere, it expands adiabatically and loses heat. WebStage 1. An area of warm air meets an area of cold air. Stage 2. The warm air is forced over the cold air Stage 3. Where the air meets the warm air is cooled and water vapour condenses. Stage 4. Clouds form and …

WebThe types of rainfall based on intensity can be classified as: Light rain – Rate of rain varies between 0 to 2.5 millimeters. Moderate rain – Rate of rain varies between 2.6 millimeters to 7.6 millimeters. Heavy rain – Rate of rain is beyond 7.6 millimeters.
WebThe region of greatest solar heating at the surface in the humid tropics corresponds to areas of deep cumulonimbus convection. Cumulonimbus clouds routinely form in the tropics where rising parcels of air are warmer than the surrounding ambient atmosphere.
