What are the four main types of air masses?

Back

The four main types of air masses are: 1. Continental Polar (cP) - cold and dry, 2. Maritime Polar (mP) - cool and moist, 3. Continental Tropical (cT) - warm and dry, 4. Maritime Tropical (mT) - warm and moist.

What is a front in meteorology?

Back

A front is a boundary between two different air masses, which can lead to changes in weather.

Front

What is a cold front?

Back

A cold front occurs when a cold air mass pushes into a warm air mass, causing the warm air to rise rapidly, often leading to thunderstorms.

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 weather changes and often resulting in rain.

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 periods of cloudy and rainy weather.

Front

What is an occluded front?

Back

An occluded front occurs when a cold front overtakes a warm front, lifting the warm air mass off the ground, often resulting in complex weather patterns.

How does convection affect air movement?

Back

Convection causes warm air to rise and cool air to sink, creating circulation patterns that influence weather.

What is high pressure in meteorology?

Back

High pressure refers to areas where the atmospheric pressure is higher than surrounding areas, often leading to clear skies and calm weather.

What is low pressure in meteorology?

Back

Low pressure refers to areas where the atmospheric pressure is lower than surrounding areas, often associated with stormy and unsettled weather.
