What are the four main types of air masses?

Back

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

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 followed by cooler temperatures.

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 periods of 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. This can lead to complex weather patterns 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 rainy weather.

Front

How does a warm front affect weather?

Back

A warm front typically brings gradual warming, increased humidity, and extended periods of light to moderate precipitation.

Front

What type of air mass is characterized as cool and moist?

Back

Maritime Polar (mP) air mass is characterized as cool and moist.

Front

What type of air mass is extremely cold and very dry?

Back

Continental Arctic (cA) air mass is extremely cold and very dry.

Front

What weather is typically associated with a cold front?

Back

Cold fronts are usually associated with thunderstorms, heavy rain, and a drop in temperature.
