A source region is an extensive region of the earth's surface where large masses of air having uniform temperature and humidity conditions characteristic of the region originate.
source region actually the answer is air masses are classified by a combination of words the 1st word represents where the air mass forms(maritime or continital) the 2nd is the temperature(polar or tropical)
A source region is an area of the earth's surface where large air masses having uniform temperature and humidity characteristic of the region originate.
Antarctica
Continental Tropical air masses (cT) A continental tropical air mass forms in the interior of subtropical continents at about 15o to 35o north and south latitude. They are hot and dry air masses due to the temperature and moisture characteristics at their source region.

a large body of air over the earth's surface---- Air Massesuniform bodies of air An air mass is a large body of air that has similar temperature and moisture properties throughout. The best source regions for air masses are large flat areas where air can be stagnant long enough to take on the characteristics of the surface below. Maritime tropical air masses (mT), for example, develop over the subtropical oceans and transport heat and moisture northward into the U.S.. In contrast, continental polar air masses (cP), which originate over the northern plains of Canada, transport colder and drier air southward. ---- ---- Once an air mass moves out of its source region, it is modified as it encounters surface conditions different than those found in the source region. For example, as a polar air mass moves southward, it encounters warmer land masses and consequently, is heated by the ground below. Air masses typically clash in the middle latitudes, producing some very interesting weather. ----
Air masses get properties of the surface beneath them from areas known as source regions. Individual regions span several million square miles in size.
The source region for the maritime tropical air mass originate over the warm waters of the southern Atlantic Ocean and the Gulf of Mexico.
Continental Tropical air masses (cT) A continental tropical air mass forms in the interior of subtropical continents at about 15o to 35o north and south latitude. They are hot and dry air masses due to the temperature and moisture characteristics at their source region.
A source in geographic terms means where the river begins in mountains or lakes.
