California is primarily affected by four air masses: maritime tropical (mT), continental tropical (cT), maritime polar (mP), and continental polar (cP). The mT air mass, originating from the Pacific Ocean, brings warm, moist conditions and is responsible for much of the state's precipitation, especially in winter. The cT air mass from the desert Southwest contributes hot, dry weather, particularly in summer. Meanwhile, the mP and cP air masses can lead to cooler temperatures and increased cloud cover, especially during winter months in Northern California.
Air masses can affect the weather because different air masses differ in temperature, density, and moisture content.

Air masses are classified according to their maritime source regions and their latitude. Different air masses affect different parts of the world.
The Hudson Bay is not an area where the maritime tropical air masses that affect north America originate.
Saskatchewan can be affected by a variety of air masses. In the summer, warm, moist air masses from the Gulf of Mexico can bring humid conditions to the province. In the winter, cold air masses from the Arctic can bring frigid temperatures and snowfall. Additionally, Pacific air masses can influence the weather in Saskatchewan, particularly in the southwest region.
Unequal heating cause air masses to form fronts. Fronts are masses that contain air that is all the same temperature and at the same altitude.

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.

prevailing westerlies are the main wind belts in north America so they push the air Masses from west to east
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.
