tropical air Air masses whose characteristics originate from a tropical source. Broadly, these comprise: (a) maritime tropical air, originating over oceans; and (b) continental tropical air, originating over land masses, and especially over N. Africa and the Middle East. Movements of these air masses poleward, with modification of their original characteristics, can have marked influence on weather in mid-latitudes.
