Cold air mass
An advancing cold front.
They form from behind the moving cold front because the warm air condenses quickly producing clouds, rain, and stormy weather.
When a cold front overtakes a warm front, it forms an occluded front. In this situation, the warm air mass is lifted off the ground as the colder air behind the cold front advances, creating a complex weather pattern with potential for thunderstorms and precipitation.
A cold front typically brings cooler temperatures, gusty winds, and a shift in weather conditions. It often causes the air to become less humid, leading to clearer skies and a decrease in precipitation. Thunderstorms and severe weather can also be associated with the passage of a cold front.
A true cold front on a weather map is associated with a boundary where cold air displaces warm air. As the cold front moves in, it can bring abrupt temperature drops, gusty winds, and sometimes storms.

A warm front behind a cold front, brings pleasant sunshine, possible some gentle rains.
A weather front can be a cold front, a warm front or an occlusion.

A cold front.
An advancing cold front.
A cold front normally moves at twice the speed of a warm front. An occluded front forms when a cold front catches up with a warm front. Occluded fronts are of two types:1. Cold occlusion : If the airmass of the advancing cold front is colder than the cool airmass of the warm front, the advancing cold front undercuts and lifts both the warm and cool airmass of the warm front. The weather is initially warm front type but during the passage of front, showery weather of cold front occurs. This occlusion is common in summer. 2. Warm occlusion : When the airmass behind the advancing cold front is less colder (cool) than the cold airmass of the warm front ahead, the advancing cold front overrides the warm front ahead. The weather in such a case is similar to that of warm front. This type of occlusion occurs in winters and is less common.

On a weather map, the symbol for a cold front is a blue line with blue triangles facing the direction that the front is moving.
