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 region and can influence the weather in areas it moves into.

Front

What does 'cP' stand for in air mass classification?

Back

'cP' stands for Continental Polar, which refers to a cold, dry air mass that forms over land in polar regions.

Front

What type of air mass is 'mT'?

Back

'mT' stands for Maritime Tropical, which is a warm, moist air mass that forms over warm ocean waters.

Front

What is a cold front?

Back

A cold front is the leading edge of a cooler air mass that is replacing a warmer air mass. It often brings thunderstorms and a drop in temperature.

Front

What is a warm front?

Back

A warm front is the leading edge of a warmer air mass that is replacing a cooler air mass. It typically brings gradual increases in temperature and precipitation.

Front

What is a stationary front?

Back

A stationary front occurs when a warm air mass and a cold air mass meet but neither has enough energy to move the other, leading to prolonged weather conditions.

Front

What type of weather is associated with a cold front?

Back

After a cold front passes, expect cool and clear skies, often following thunderstorms.

Front

What type of weather is associated with a warm front?

Back

Warm fronts typically bring steady rain or light precipitation, followed by warmer temperatures.

Front

Where does a maritime polar (mP) air mass originate?

Back

A maritime polar (mP) air mass originates over cold ocean waters, bringing cool and moist conditions.

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, often leading to complex weather patterns.
