What does Maritime have to do with air masses?

Maritime tropical air masses originate over the warm waters of the tropics and Gulf of Mexico, where heat and moisture are transferred to the overlying air from the waters below. The northward movement of tropical air masses transports warm moist air into the United States, increasing the potential for precipitation.

Why is maritime Arctic left out of the air mass classifications?

Why is Maritime Arctic left out of the air-mass classifications? They only rarely occur. Air mass source regions tend to be dominated by: slow moving anticyclones.

What happens when a continental polar air mass collides with a maritime tropical air mass?

Storms may occur when continental polar air masses move south and collide with maritime tropical air masses moving north.

How are air masses modified?

Air masses can become modified as they move away from their source region. In its source region an air mass gains properties which are characteristic of the underlying surface. It may be cold or warm and it may be dry or moist. Polar air is stable because it has been cooled from below.

Do air masses change as they move?

One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream. Air masses modify once they move out of their source region. For example, a cold air mass will modify (warm up in this case) as it moves over warmer land in lower latitudes.

Can air masses move?

The Movement of Air Masses: transporting warm air northward and colder air southward. Counterclockwise winds associated with cyclones transport heat and moisture from lower to higher latitudes and play a significant role in the movement of air masses.

What do the letters K and W mean when attached to an air mass?

the air mass AND its abbreviation). What do the letters “K” or “W” mean when attached to an air mass? The “K” means that the air moving across a region is colder than the land surface temperature while “W” indicates that the air is warmer than the land surface temperature. 4.
