What is the best source region for an air mass?
The main source regions are the high pressure belts in the subtropics (giving rise to tropical air masses) and around the poles (the source for polar air masses).

What are the source regions of airmass?
Air masses are commonly classified according to four basic source regions with respect to latitude. These are Polar (cold), Arctic (very cold), Equatorial (warm and very moist), and Tropical (warm).

What are the characteristics of a good air mass source region?
They have relatively uniform temperature and moisture content; the region separating two different air masses is called a front. Air masses form in “source regions” where there is little topography and relatively stagnant winds near the surface.

What are the characteristics of a good air mass source region?
If an area is described as a “good air mass source region,” what information can you give about it? That the area is long, flat, and uniform for air masses to originate and retain similar properties with the surface below it, such as arctic plains and warm oceans.

What should be the source region of a huge mass of air in order for it to develop uniform characteristics?
In order for a huge mass of air to develop uniform characteristics, its source region should be generally flat and of uniform composition with light surface winds. Therefore, ideal source regions are usually those areas dominated by surface high pressure systems.

What is an air mass region?
An air mass is a large body of air with generally uniform temperature and humidity. The area over which an air mass originates is what provides its characteristics. The longer the air mass stays over its source region, the more likely it will acquire the properties of the surface below.

Which are source regions of continental tropical air masses?
CONTINENTAL TROPICAL AIR MASS. The source region for cT air is the desert Southwest, the high plains and Mexico with relation to the United States. The air has low dewpoints and warm to hot afternoon temperatures but with mild nighttime temperature. Skies are generally clear in cT air.

What are the characteristic of an air mass source region?
Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the the underlying surface properties where they originate.

What are the characteristics of each of the 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.
