Answer:
Air Front
Explanation:
The transition zone between two distinct air mass is known as the front. The presence of the air front in an area indicates the change in the weather pattern causing heavy rainfall, thunderstorms, hurricanes, tornadoes, and blustery wind.
This air front is mainly divided into 4 types. They are as follows-
(1) Warm air front- In this type of front, the warm air replaces the cold air mass.
(2) Cold air front- In this type of front, the cold air replaces the warm air.
(3) Occluded air front- When a warm air mass occurs in between two cold air mass, then it is known as the occluded air. It results in heavy rainfall and powerful wind.
(4) Stationary air front- When both the warm and cold air occurs simultaneously and there occurs no replacement of one another, then it is known as the stationary type of air front.
