Air masses and 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 source region and can influence weather patterns.

Front

What are the four main types of air masses?

Back

The four main types of air masses are: 1. Continental Polar (cP) - cold and dry, 2. Maritime Polar (mP) - cold and humid, 3. Continental Tropical (cT) - warm and dry, 4. Maritime Tropical (mT) - warm and humid.

Front

What is a front in meteorology?

Back

A front is a boundary between two different air masses, which can lead to changes in weather conditions.

Front

What is a warm front?

Back

A warm front occurs when a warm air mass slides over a cold air mass, often resulting in gradual temperature increases and light precipitation.

Front

What is a cold front?

Back

A cold front occurs when a cold air mass moves into a warm air mass, leading to a rapid drop in temperature and often severe weather.

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 rainy weather.

Front

What is an occluded front?

Back

An occluded front occurs when a cold front overtakes a warm front, causing the warm air mass to be lifted off the ground, often resulting in complex weather patterns.

Front

How does a warm front affect weather?

Back

A warm front typically brings gradual increases in temperature, extended periods of light rain, and can lead to clear skies after the front passes.

Front

How does a cold front affect weather?

Back

A cold front usually brings a sudden drop in temperature, heavy rain, thunderstorms, and can lead to clear skies after the front passes.

Front

What weather is associated with a stationary front?

Back

Stationary fronts are associated with prolonged cloudy weather and steady precipitation, as the air masses remain in place.
