Weather Fronts

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 forms when a cold front overtakes a warm front, causing the warm air to be lifted off the ground. It is represented by purple humps and triangles on weather maps.

Front

What type of air is more dense and tends to sink?

Back

Cold air is more dense than warm air and tends to sink.

Front

What weather is associated with High Pressure systems?

Back

High pressure systems are associated with clear, sunny weather and stable atmospheric conditions.

Front

What is a Cold Front?

Back

A cold front occurs when a cold air mass pushes into a warmer air mass, often leading to thunderstorms and a drop in temperature.

Front

What is a Warm Front?

Back

A warm front occurs when a warm air mass moves over a cold air mass, leading to gradual warming and often resulting in light rain.

Front

What is a Low Pressure system?

Back

A low pressure system is associated with rising air, which can lead to cloud formation and precipitation.

Front

What type of front is represented by red semicircles on weather maps?

Back

A warm front is represented by red semicircles on weather maps.

Front

What is the significance of air pressure in weather systems?

Back

Air pressure influences weather patterns; high pressure generally leads to fair weather, while low pressure can lead to storms.

Front

What happens when a Cold Front meets a Warm Front?

Back

When a cold front meets a warm front, the cold air pushes the warm air upwards, often resulting in stormy weather.
