Weather Fronts and Air Masses

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, such as land or water.

Front

What are the two main types of air masses?

Back

The two main types of air masses are maritime (formed over water) and continental (formed over land).

Front

What is a maritime tropical air mass?

Back

A maritime tropical air mass is warm and humid, forming over warm ocean waters, typically near the equator.

Front

What is a continental polar air mass?

Back

A continental polar air mass is cold and dry, forming over land in polar regions.

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.

Front

What happens when a warm front meets a cold front?

Back

When a warm front meets a cold front, the warm air rises over the cold air, often leading to precipitation.

Front

What is a stationary front?

Back

A stationary front occurs when two air masses meet but neither moves, leading to prolonged weather conditions.

Front

What does a 'L' indicate on a weather map?

Back

A 'L' indicates a low pressure system, which is often associated with cloudy and rainy weather.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from clouds to the ground.

Front

What is an occluded front?

Back

An occluded front occurs when a cold front overtakes a warm front, leading to complex weather patterns.
