How do air masses and fronts influence the weather?
Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
What are the major air masses that influence the weather?
Four major types of air masses influence the weather in North America: maritime tropical, continental tropical, maritime polar, and continental polar.
How do air masses affect weather in North America?
The turbulence of the two air masses moving together can cause clouds and thunderstorms to form. The border between two air masses at the Earth’s surface is called weather front. Air masses are given a two-part name that describes the humidity and temperature characteristics of the region where they form.
What air mass brings the coldest weather to the US?
Continental arctic air
Continental arctic air is much colder and drier than continental polar air. Temperatures associated with continental arctic air are often below zero in northern parts of the United States.
Which air masses have the greatest effect on weather conditions in much of the United States?
Continental Polar and Maritime Tropical air masses have the greatest effect on weather conditions in much of the United States.
What air mass influences the weather of the Pacific more than any other?
Maritime polar air masses, abbreviated mP on weather maps, tend to dominate the Pacific coast region. These air masses form over a cold ocean current in the northern Pacific Ocean.
