A body of air in which horizontal gradients of temperature and humidity are relatively slight and which is separated from an adjacent body of air by a more or less sharply defined transition zone (front) in which these gradients are relatively large. 2, record 2, English, - air%20mass
Record number: 2, Textual support number: 1 CONT
The horizontal dimensions of air masses are normally hundreds or even thousands of kilometres. Air masses are classified into groups designated as "polar" (P) or "tropical" (T), maritime (m) or continental (c), defining the basic temperature and humidity characteristics, respectively; more generally, a twofold classification in terms of both elements, e.g. mT or cP, is used. Further divisions are sometimes made into Arctic or Antarctic (A) air and into classes of more local significance, e.g. Mediterranean air. 2, record 2, English, - air%20mass
