Conventional rain
- Convectional rainfall is a type of rainfall that involves the formation of convection currents.
- This rainfall occurs when the temperature gets high and the warmer air rises up in the atmosphere. On expansion, this air cools down and clouds are formed, which are generally cumulus clouds.
- These clouds bring rainfall which lasts for a very short duration.
- Such rainfall is known as convectional rainfall which occurs mainly in the northern hemisphere, predominantly in the tropical regions.
Cyclonic rain
- The cyclonic rainfall, on the other hand, is caused due to cyclones. A cyclone has a warm front and a cold front with a substantial difference in the temperatures.
- A cyclone has a warm front and a cold front with a substantial difference in the temperatures. This difference causes the air above the warm front to rise up and expand. The expansion causes the temperature to drop and condensation occurs, which results in the formation of clouds.
- These clouds bring heavy rainfall which may even go on for several days.
- This type of rainfall is known as cyclonic rainfall and generally occurs in the coastal areas of the world.
