Types Of Air Masses Flashcards
Cold air masses come from
Polar areas
Warm air masses come from
Tropical areas
What are air masses that form over the ocean called
Maritime
Air masses that form overland are called
Continental
Name three large landmass is over which continental air masses form
Northern Canada, Northern Asia, and the southwestern United States
What weather conditions do continental air mass is generally bring when they move into a region
They bring dry weather condition
Name and describe the two types of continental air masses
Continental polar air masses are cold and dry. Continental tropical air masses are warm and dry.
How do air masses that form over the ocean differ from continental air masses
The humidity in the these air masses tend to be higher than that of continental air masses
What weather conditions do maritime air masses generally bring when they move to a new location
They bring precipitation and fog
Name and describe the two types of maritime air masses
Maritime polar air masses are moist and cold. Maritime tropical air masses are moist and warm
List the four types an air masses that affect the weather of North America, and list their six source location
Continental polar – Canada maritime polar– Polar pacific,polar atlanticcon continental tropical – United States Southwest maritime tropical – tropical Pacific, tropical Atlantic
What type of the weather does air mass usually bring
The weather of it’s source location
What may happen to an air region as it moves away from its source region
It may change. For example cold dry air may become warmer and more moist as it moves from land to a warm ocean
What develops when cold dry air becomes warm and moist
Clouds and precipitation
Describe the weather brought to the eastern United States by maritime tropical air masses that form over the tropical Atlantic ocean
They bring mild often cloudy weather in the winter
How does the weather brought to the Pacific coast of the United States by maritime tropical air masses that form over the tropical Pacific ocean differ between the summer and winter
Summer – human hot weather. Winter – moderate precipitation
Explain where continental polar air masses generally originate, where they moved, and the type of whether they bring
They form over are you still in snow-covered land.they moved to the northern United States and can reach as far south as the gold coast of the US. In the summer they bring cold,dry weather. In winter,they bring cold weather to northern US. They come from northern Canada and northern pacific and Atlantic Ocean.
Describe maritime polar air masses that form over the North Pacific ocean in the type in whether they bring
They are very moist but not as cold as continental Canadian polar air masses
How do you continental polar Canadian air masses differ from the polar air masses that form over North Pacific ocean
Maritime polar air masses are not as cold as continental polar Canadian air masses
How do maritime polar Atlantic air masses differ in movement in weather conditions from the maritime Pacific air masses
Maritime polar Atlantic air masses move east toward europe but also West over new England in eastern Canada. In winter they bring cold cloudy weather and snow. In the summer these can produce cool weather,low clouds and fog.
Air masses are classified according to
Source region
