Air Pressure and Fronts Flashcard

Front

What is a cold front?

Back

A cold front is a boundary between a cold air mass and a warm air mass, where the cold air pushes under the warm air, often leading to precipitation.

Front

What is a warm front?

Back

A warm front is a boundary where a warm air mass rises over a cold air mass, typically bringing gradual increases in temperature and precipitation.

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, often leading to prolonged periods of cloudy and wet weather.

Front

What is an occluded front?

Back

An occluded front forms when a cold front overtakes a warm front, causing the warm air to be lifted off the ground, often resulting in complex weather patterns.

Front

What does high pressure indicate in weather systems?

Back

High pressure usually indicates clear skies and calm weather, as air descends and warms, preventing cloud formation.

Front

What does low pressure indicate in weather systems?

Back

Low pressure typically brings clouds and precipitation, as air rises and cools, leading to condensation.

Front

How does air move in relation to pressure areas?

Back

Air moves from high pressure areas to low pressure areas.

Front

What happens to an air mass that is rising?

Back

An air mass that is rising is usually warm and less dense, which allows it to rise.

Front

What type of weather is associated with a low-pressure system?

Back

A low-pressure system is associated with cloudy skies and precipitation.

Front

What type of weather is associated with a high-pressure system?

Back

A high-pressure system is associated with clear skies and dry weather.
