Air masses and fronts

Front

What is an air mass?

Back

An air mass is a large body of air that has uniform temperature and humidity characteristics. It forms over a specific region and can influence the weather in areas it moves into.

Front

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.

Front

What is a front in meteorology?

Back

A front is a boundary between two different air masses. It is where the characteristics of the air masses change, leading to various weather conditions.

Front

What is a cold front?

Back

A cold front occurs when a colder air mass pushes into a warmer air mass, causing the warm air to rise rapidly, 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 colder air mass, leading to gradual warming and often resulting in steady 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, 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.

Front

How do you calculate relative humidity?

Back

Relative humidity is calculated by dividing the amount of water vapor in the air by the maximum amount of water vapor the air can hold at that temperature, then multiplying by 100.

Front

What does high humidity indicate?

Back

High humidity indicates that there is a lot of evaporated water in the air, which can make the air feel warmer and more uncomfortable.

Front

What is the typical weather associated with a continental tropical air mass?

Back

A continental tropical air mass is typically dry and warm, often leading to hot and dry weather conditions.
