Explanation:

Orographic Rainfall: When the saturated air mass comes across a mountain, it is forced to ascend and as it rises, it expands (because of fall in pressure); the temperature falls, and the moisture is condensed.
Example: Western Ghats
Cyclonic Rain: The precipitation in a tropical cyclone is of convectional type while that in a temperate cyclone is because of frontal activity.
Conventional Rainfall: The, air on being heated, becomes light and rises up in convection currents. As it rises, it expands and loses heat and consequently, condensation takes place and cumulous clouds are formed. This process releases latent heat of condensation which further heats the air and forces the air to go further up. It is heavy but of short duration, highly localised and is associated with minimum amount of cloudiness.
