The four are Maritime tropical, Continental tropical, maritime polar, and Continental polar
Air masses can affect the weather because different air masses differ in temperature, density, and moisture content.

There are five main types of air masses that affect the weather in the US: continental polar, continental tropical, maritime polar, maritime tropical, and Arctic. These air masses can bring different weather conditions as they move across the country.

The five types of air masses that affect weather in the U.S. are Continental Polar (cP), Maritime Polar (mP), Continental Tropical (cT), Maritime Tropical (mT), and Continental Arctic (cA). cP air masses bring cool, dry conditions, while mP air masses are cool and moist. cT air masses are hot and dry, and mT air masses are warm and humid. cA air masses, which are less common, are extremely cold and dry, primarily influencing weather in the northern regions.

cpThe air masses with the least influence on the weather of North America are the continental tropical air masses.

Maritime tropical air masses affecting North America usually originate over the warm waters of the Gulf of Mexico and the Caribbean Sea. These air masses bring warm and moist air to regions along the Gulf Coast and eastern U.S., influencing weather patterns in those areas.
prevailing westerlies are the main wind belts in north America so they push the air Masses from west to east
