What are the different types of Rainfall? Back

Remember the process of rainfall formation is always the same:

  1. AIR RISES
  2. AIR COOLS
  3. AIR CONDENSES
  4. CLOUDS FORM AND PRECIPITATION OCCURS

What differs is what causes the air to rise in the first place..

Type of RainfallExplanation

Relief Rainfall forms where moist air is forced to rise over mountains or hills. As the air rises it begins to cool and condenses. As the water vapour condenses back to water droplets, clouds are formed. As the clouds grow bigger it starts to rain.

Convectional rainfall forms due too heating of the ground by the sun. As the air close to the ground is heated it becomes lighter and begins to rise. When the air rises it begins to cool and condense. As the water vapour condenses back to water droplets, clouds are formed. As the clouds grow bigger it starts to rain.Frontal rainfall occurs where warm air meets cold air. The warm air is lighter than cold air and it is therefore forced to rise above it. As the air rises it begins to cool and condense. As the water vapour condenses back to water droplets, clouds are formed. As the clouds grow bigger it starts to rain.
