WebAreas of low pressure are known as depressions. Depressions occur when warm air meets cold air. The point where warm air meets cold air is called a front. Along the front, there is usually cloud and rainfall. This occurs because the warm air cools and condenses when it meets the cold air (you can find out more about frontal rainfall here ).
