Weather Variables, Fronts, Air Masses, and Global Winds Test

Front

What is an Occluded Front?

Back

An occluded front occurs when a cold front overtakes a warm front, causing the warm air to be lifted off the ground. This often leads to complex weather patterns and precipitation.

Front

What tool is used to measure wind speed?

Back

An anemometer is used to measure wind speed.

Front

What type of air mass is represented by 'cP'?

Back

'cP' stands for Continental Polar, which is a cold, dry air mass that forms over land in polar regions.

Front

What happens to air pressure when warm air rises?

Back

When warm air rises, it creates low pressure, which can lead to rain.

Front

What is a Cold Front?

Back

A cold front is the leading edge of a cooler mass of air, replacing a warmer mass of air. It often brings thunderstorms and a drop in temperature.

Front

What is a Warm Front?

Back

A warm front is the leading edge of a warmer mass of air, replacing a cooler mass of air. It typically brings gradual temperature increases and prolonged 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, leading to prolonged cloudy and rainy weather.

Front

What is a Maritime Polar (mP) air mass?

Back

A Maritime Polar (mP) air mass is a cool, moist air mass that forms over oceans in polar regions.

Front

What is the role of a Barometer?

Back

A barometer is an instrument used to measure atmospheric pressure, which helps in weather forecasting.

Front

What type of weather is associated with high pressure?

Back

High pressure is generally associated with clear skies and calm weather.
