When two opposite – natured air – masses (cold and hot) blow in, they try to retain their identity related to temperature and humidity. In this process, a sloping border develops in between, which is called front.
Types of front:
The fronts are mainly divided into the following parts:
1. Warm Front: The front which originates by warm air advances over the cold air.
2. Cold Front: The front which originates by cold air advancing over the warm air.
3. Stationary Front: Front which originates due to the two opposing fronts being parallel.
4. Occluded Front: Occluded front is formed when a cold air – mass overtakes a warm air – mass and goes beneath it.
