Chapter 9: Air Masses and Fronts
Air mass source regions occur only in the high or low latitudes; middle latitudes are too variable. Air masses are classified according to the temperature and moisture characteristics of their source

Air masses are born in a source region where they take on their characteristic temperature and moisture content. Source regions are often regions of low relief and calm wind that prevent turbulent mixing

Air masses are vast volumes of air that form the foundational elements of global weather patterns. They are defined by their relatively uniform temperature and moisture content, acquired
View Details
Air masses form over large surfaces with uniform temperatures and humidity, called source regions. Low wind speeds let air remain stationary long enough to take on the features of the

Air masses form in source regions, which are extensive, uniform surfaces like vast oceans or continental plains. For uniform properties to develop, air must remain stagnant over the source region for several

OverviewClassification and notationCharacteristicsMovement and frontsModification
In meteorology, an air mass is a volume of air defined by its temperature and humidity. Air masses cover many hundreds or thousands of square miles, and adapt to the characteristics of the surface below them. They are classified according to latitude and their continental or maritime source regions. Colder air masses are termed polar or arctic, while warmer air masses are deemed tropical. Continental and superior air masses are dry, while maritime and monsoon air masses are moist. Weather fronts separat

Where an air mass receives it''s characteristics of temperature and humidity is called the source region. Air masses are slowly pushed along by high-level winds, when an air mass moves over a new

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).

Air masses can cover hundreds of thousands of square miles. Air mass source regions are geographic areas where an air mass originates. Source regions should be: The longer the air mass stays over its

Polar air masses, designated by the letter "P", originate over the higher latitudes of both land and sea and are therefore not as cold as Arctic air masses. Tropical air masses, designated by
