Study Notes

Air Mass Classification

Air masses are classified based on moisture content and temperature.

Definition of Air Mass

An air mass is a significant volume of air characterized by uniform temperature and moisture.

Types of Air Masses

There are four primary types of air masses:
- Continental Polar
- Continental Tropical
- Maritime Polar
- Maritime Tropical

Anticyclone

An anticyclone is defined as high-pressure air that rotates opposite to the direction of Earth's rotation.

Cyclone

A cyclone is a low-pressure area with winds spiraling towards its center, indicating an inward flow of air.

Fronts

A front serves as the boundary between air masses with differing densities and temperatures.

Warm Front Formation

A warm front forms when a warm air mass moves over a receding cold air mass.

Cold Front Formation

A cold front occurs when a cold air mass pushes under a warm air mass.

Coldest Location

Northern Canada is identified as the coldest region.

Warmest Location

Areas near the Equator are recognized as the warmest regions.
