What is a warm front?

Back

A warm front occurs when a warm air mass moves over a cold air mass. It typically brings gradual increases in temperature and can lead to precipitation.

What is a cold front?

Back

A cold front occurs when a cold air mass pushes into a warm air mass. It often leads to sudden temperature drops and can cause thunderstorms.

What is an occluded front?

Back

An occluded front forms when a cold front overtakes a warm front, lifting the warm air mass off the ground. It can lead to complex weather patterns.

What is a stationary front?

Back

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

How do we characterize an air mass that forms over the ocean?

Back

An air mass that forms over the ocean is characterized as 'wet' due to the moisture it absorbs from the water.
