What is an occluded front?

Back

An occluded front occurs when a cold front overtakes a warm front, causing the warm air to be lifted off the ground. This can lead to complex weather patterns.

What happens to air when it warms?

Back

When air warms, it becomes less dense and tends to rise, which can lead to low-pressure systems.
