Air Masses and Weather Fronts

Front

What is an air mass?

Back

An air mass is a large body of air that has uniform temperature and humidity characteristics. It forms over a specific area and can influence the weather in regions it moves into.

Front

What are the two main types of air masses?

Back

The two main types of air masses are maritime (formed over water) and continental (formed over land).

Front

What is a maritime polar air mass?

Back

A maritime polar air mass is a cold, moist air mass that forms over the northern oceans and brings cool, wet weather.

Front

What is a continental tropical air mass?

Back

A continental tropical air mass is a warm, dry air mass that forms over land in the tropics and brings hot, dry weather.

Front

What is a warm front?

Back

A warm front is the boundary where a warm air mass replaces a cold air mass, often bringing gradual increases in temperature and precipitation.

Front

What is a cold front?

Back

A cold front is the boundary where a cold air mass pushes into a warm air mass, often causing sudden drops in temperature and thunderstorms.

Front

What is a stationary front?

Back

A stationary front is a boundary between two air masses that are not moving, leading to prolonged periods of cloudy and wet weather.

Front

What is an occluded front?

Back

An occluded front occurs when a cold front overtakes a warm front, causing complex weather patterns and often leading to precipitation.

Front

What is a cyclone?

Back

A cyclone is a weather system characterized by low pressure, where winds blow counterclockwise in the Northern Hemisphere, often bringing stormy weather.

Front

What is an anticyclone?

Back

An anticyclone is a weather system characterized by high pressure, where winds blow clockwise in the Northern Hemisphere, usually bringing clear skies.
