Air Masses, Fronts, and Pressure Systems

Front

What is an air mass?

Back

An air mass is a large body of air that has uniform temperature and humidity characteristics. They form over land or water and can affect the weather in the regions they move into.

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) - cool and moist, 3. Continental Tropical (cT) - warm and dry, 4. Maritime Tropical (mT) - warm and moist.

Front

What is a front in meteorology?

Back

A front is a boundary between two different air masses. It is where the characteristics of the air masses change, leading to various weather conditions.

Front

What is a warm front?

Back

A warm front occurs when a warm air mass moves over a cold air mass. It typically brings gradual increases in temperature and steady precipitation.

Front

What is a cold front?

Back

A cold front occurs when a cold air mass pushes into a warm air mass. It often leads to sudden temperature drops and can cause thunderstorms.

Front

What is a stationary front?

Back

A stationary front occurs when two air masses meet but neither is strong enough to replace the other. This can lead 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, lifting the warm air mass off the ground. This can lead to complex weather patterns and precipitation.

Front

What weather is typically associated with high pressure systems?

Back

High pressure systems are generally associated with clear skies and nice weather. They indicate stable atmospheric conditions.

Front

What weather is typically associated with low pressure systems?

Back

Low pressure systems are often associated with cloudy skies, precipitation, and stormy weather. They indicate unstable atmospheric conditions.

Front

What does the symbol 'H' represent on a weather map?

Back

The symbol 'H' represents a high pressure system on a weather map.
