What change would an air mass modification cause in a continental polar air mass moves south over the central United States?

What change would an air mass modification cause in a continental polar air mass moves south over the central United States?

Continental polar air masses in winter cause severe cold waves when they move southward through Canada and into the Central and Eastern United States. If a cP air mass moves southward into the Mississippi Valley and then into the Southeast, it will gradually warm up but remain dry.

What happens when a continental polar air mass moves over warm water?

As air moves over earths surface, the characteristics of the surface begin to change the air mass. For example, if a continental polar air mass moves over warm water, The air near the surface will become warmer and gain moisture. These changes begin where the air touches the surface. Clouds can form in this rising air.

How does air mass modification influence weather conditions as air masses move from one location to the next?

Movement of Air Masses When a new air mass moves over a region it brings its characteristics to the region. This may change the area’s temperature and humidity. Moving air masses cause the weather to change when they contact different conditions. Warm air masses tend to move toward the poles.

How are continental tropical and continental polar air masses alike and how are they different?

Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold.

Where would a continental tropical air mass form?

Continental Tropical (cT): Hot and very dry. They usually form over the Desert Southwest and northern Mexico during summer. They can bring record heat to the Plains and the Mississippi Valley during summer, but they usually do not make it to the East and the Southeast.

Where are continental polar air masses?

Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable. These air masses originate over northern Canada and Alaska as a result of radiational cooling. They move southward, east of Rockies into the Plains, then eastward.

Where are polar air masses formed?

Arctic air masses form in the Arctic region and are very cold. Tropical air masses form in low-latitude areas and are moderately warm. Polar air masses take shape in high-latitude regions and are cold. Equatorial air masses develop near the Equator, and are warm.

What does air mass modification cause in a continental polar air mass?

What change would air mass modification cause in a continental polar air mass that moves south over the central US Changes hot and dry as it moves Maritime polar cool and humid maritime tropical warm and humid continental polar dry and cold continental tropical dry and hot arctic very cold and dry Differences of continental and maritime air masses?

What happens when a polar air mass moves south?

For example, a continental polar air mass moves south into the United States will be designated cPk. When an air mass moves over a colder surface, it will be cooled from below. This will cause the lower levels to become more stable. As you have already learned, stable conditions means little vertical motion and stratiform clouds and fog.

What kind of air masses affect the United States?

Five air masses affect the United States during the course of a typical year: continental polar, continental arctic, continental tropical, maritime polar, and maritime tropical. Continental air masses are characterized by dry air near the surface while maritime air masses are moist.

Which is the best description of continental air masses?

Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold. Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable.
