Strahler climate classification A little-used system for describing climates devised in 1969 by A. N. Strahler, in which world climates are related to the main air masses that produce them, as: (a)equatorial/tropical air masses, producing low-latitude climates;(b)tropical and polar air masses, producing mid-latitude climates; and(c)polar and Arctic air masses, producing high-latitude climates. Subsets of these are based on variations in temperature and precipitation to give 14 regional types, plus upland (highland) climates which are regarded as a separate category. See also Köppen climate classification and Thornthwaite climate classification.
