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 specific area and takes on the properties of that area.

Front

What are the four main types of air masses?

Back

The four main types of air masses are: cP (continental Polar), cT (continental Tropical), mP (maritime Polar), and mT (maritime Tropical).

Front

What does 'cP' stand for in air masses?

Back

'cP' stands for continental Polar, which refers to cold and dry air masses that form over land in polar regions.

Front

What does 'mT' stand for in air masses?

Back

'mT' stands for maritime Tropical, which refers to warm and moist air masses that form over warm ocean waters.

Front

What is a cold front?

Back

A cold front is the leading edge of a cooler air mass that replaces a warmer air mass. It typically brings short, intense storms.

Front

What is a warm front?

Back

A warm front is the leading edge of a warmer air mass that replaces a cooler air mass. It usually brings gradual increases in temperature and longer-lasting precipitation.

Front

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 and creating clouds and precipitation.

Front

What is a stationary front?

Back

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

Front

How does a cold front affect weather?

Back

A cold front can cause rapid temperature drops, strong winds, and severe thunderstorms due to the lifting of warm air.

Front

How does a warm front affect weather?

Back

A warm front typically leads to gradual temperature increases, overcast skies, and steady rain as warm air rises over cooler air.
