Air Masses and Weather Fronts

Front

What is convection?

Back

Convection is the process of heat transfer in fluids (liquids and gases) where warmer, less dense air rises and cooler, denser air sinks, creating a circulation pattern.

What is an occluded front?

Back

An occluded front is a weather front that occurs when a cold air mass overtakes a warm air mass and lifts it off the ground, often leading to precipitation.

Front

What happens during a cold front?

Back

During a cold front, a cold air mass pushes into a warm air mass, causing the warm air to rise rapidly, which can result in thunderstorms and heavy rain.

What are prevailing winds?

Back

Prevailing winds are winds that blow predominantly in one direction and are responsible for the movement of air masses across the globe.

What is a warm front?

Back

A warm front is a weather front that occurs when a warm air mass moves over a cold air mass, leading to gradual temperature increases and often light rain.

What is a stationary front?

Back

A stationary front is a weather front that occurs when two air masses meet but neither is strong enough to replace the other, leading to prolonged periods of cloudy weather and precipitation.

What is the role of the jet stream in weather?

Back

The jet stream is a fast-flowing air current in the upper atmosphere that influences weather patterns and the movement of air masses.
