Rain occurs everywhere in the world everyday. It is very common and many people knows how it is formed. But there are actually different types of rain. Frontal rainfall is a type of rainfall. This is how it is formed:
- The warm air rises faster than the cold air as it is less dense.
- When the 2 types of air meet, the warmer air which is lighter rises over the cold air.
- The warm air then cools down as it is high.
- Clouds are then formed by the warm air.
- Front is where the warm air meets the cold air. Frontal rainfall is very common in Britain, especially during the winter.
