Air Pressure and Fronts

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a surface. It decreases with altitude.

Front

What does a cold front symbol look like?

Back

A cold front is typically represented by a blue line with triangles pointing in the direction of movement.

Front

What weather is associated with a warm front?

Back

Warm fronts usually bring gradual warming and can lead to overcast skies and light rain.

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 cloudy and rainy weather.

Front

What type of weather does a high pressure system bring?

Back

High pressure systems generally bring clear skies and fair weather.

Front

What is the difference between high pressure and low pressure?

Back

High pressure is associated with sinking air and clear skies, while low pressure is associated with rising air and stormy weather.

Front

What does an occluded front indicate?

Back

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

Front

How does air pressure affect weather?

Back

Changes in air pressure can lead to different weather conditions; low pressure often brings storms, while high pressure brings calm weather.

Front

What is the symbol for a low pressure system?

Back

A low pressure system is represented by a red 'L' on weather maps.

Front

What happens to air pressure as altitude increases?

Back

Air pressure decreases as altitude increases because there is less air above the surface.
