Cross-sectional view of a typical cold front.
Cross-sectional view of a typical warm front.
An occluded front is formed from the “collapsing” of a mid-latitude
wave cyclone because the cold front moves faster than the warm front.
As the cold front “catches up to” and overtakes the warm front
the warm air is lifted off the ground and occlusion has begun.
Occlusion continues as the cold front proceeds to push all the warm air
off the surface until the system has used all its energy and run its course.

associated weather map symbols.
