What is a warm front?

Back

A warm front occurs when a warm air mass moves over a cold air mass. This can result in gradual temperature increases and often brings steady rain.

What is a stationary front?

Back

A stationary front occurs when two air masses meet but neither is strong enough to replace the other. This can lead to prolonged periods of cloudy and rainy weather.

What is an occluded front?

Back

An occluded front occurs when a cold front overtakes a warm front, lifting the warm air mass off the ground. This can lead to complex weather patterns and precipitation.
