Exploring the Five Types of Air Masses

The video explains air masses, their types, and their impact on North America. It covers maritime and continental air masses, including tropical, polar, and arctic types. The movement of air masses is influenced by wind currents, the Coriolis effect, and pressure systems. Specific air masses like maritime tropical and polar, as well as continental tropical and polar, are discussed in detail, highlighting their characteristics and effects. The video also explores how cyclones and anticyclones can move air masses.

What defines an air mass?

• A large body of air with similar temperatures, humidity, and dew points

• A small body of air with similar temperatures and humidity

• A small body of air with varying temperatures

• A large body of air with different temperatures and humidity
