Air masses are large masses of air with and one for the temperature. Dry air masses are similar moisture and temperature classified as continental ( c ) and moist air characteristics. Those two factors along with masses are classified as maritime ( m ) . Warm their source region help name the masses. air masses are classified as Tropical (T) and They develop and take on the characteristics of cool/cold air masses are classified as Polar ( P ) . the surfaces they form above. Air masses that The two-letter representation displays the form at higher latitude tend to be cooler in moisture content as a lowercase letter and the temperature and those that form at lower temperature as an uppercase letter. The four latitudes tend to be higher in temperature. most common air masses are defined in table 2 Similarly air masses that form over or near a below. It is important to note that these water body tend to be moister than those that descriptors are relative and not absolute. There form away from water or overland, which are is not a base level or moisture or temperature dry. Using moisture and temperature that an air mass needs to have in order to be characteristics we can define air masses using a defined. two-letter code, one for the moisture content Table 2: Principle air masses in the United States 1. Based on the information and table below determine the geographic area in the United States most likely to allow the formation of each air mass type. (1 pt each) a. mP : b. CP : c. mT : d. CT:.
