Huge air masses move around and bump into each other but they don’t mix very well because of differences in density and temperature. The area or edge where the air masses meet and do not mix becomes a front (battle area).
When air masses meet at a front, the collision often causes storms and changeable weather.
There are four types of fronts:
The kind of front that develops depends on the characteristics of the air masses and how they are moving!
Stationary Front Symbol the direction the front is moving.
