Where Do Fronts Form?

Warm fronts often form on the east side of low-pressure systems where warmer air from the south is pushed north. You will often see high clouds like cirrus, cirrostratus, and middle clouds like altostratus ahead of a warm front. These clouds form in the warm air that is high above the cool air.

Where do fronts develop?

Fronts develop at the boundary where two air masses with different temperatures—and, usually, different humidities—come into contact with each other. The term front was suggested by the Bjerkneses because the collision of two air masses reminded them of a battlefront during a military operation.

How do fronts form?

A textbook example of a frontal system is when a warm, most air mass from the south moves towards cooler air to the north. In between these two air masses create a warm front. A cold front forms when a very cold air mass, most likely from the west, moves toward and take over the warm air mass.
