Convective Rainfall Heating from the sun warms the land, to cause lifting. As the air rises, it cools and condenses to form clouds. If the clouds grown in sufficient height, it rains.

Relief / Orographic Rainfall As the air comes ashore, it is forced to lift, causing it to cool and condense. As it condenses, clouds form to produce rain. Lea side of the mountain has very little rain, since it has been dropped already – producing the rain shadow.

Frontal Rainfall A cold wedge of air acts like a mountain, causing the lighter warmer air to rise. As the air rises it cools, condenses and clouds form to produce rain.

Rainfall Summary Convective rainfall occurs in warm places, especially in the afternoon (after the max heating). Orographic rainfall is common in mountainous and coastal locations where the air is forced to rise. Frontal rainfall is caused be the meeting of two air masses, which creates a ‘front’ which separates warm and cool air – forcing the air to lift.
