2. CONVECTIONAL This type os rainfall is characteristic of hot climates The Sun heats the ground and water evapores As water vapour rises, it cools When water vapour cools, it condenses and forms droplets that form clouds and fall to the Earth as rain.

3. OROGRAFIC OR RELIEF This type of rainfall is characteristic of mountainous regions Hot, humid air from the sea reaches a mountain. The air raises and cools. Clouds form, and it rains on the windward side of the mountain, the side which receives the ocean air. It does not rain on the other side.

4. FRONTAL This type of rainfall takes place at the boundary, or front, between a mass of warm air and a mass of cold air. A mass of hot, humid air meets a mass of cold air. The mass of hot air weighs less and rises above the mass of cold air. When it rises, it cools. Clouds form and it rains.
