What form when an active cold front overtakes a warm front?

When an active cold front overtakes a warm front, it creates a type of front known as an occluded front. This occurs when the colder air mass moves faster than the warm air mass, lifting the warm air off the ground entirely. As a result, the warm air is displaced, leading to the development of clouds and precipitation. Occluded fronts are often associated with complex weather systems, including storms and precipitation patterns.
