tropospheren.

Brit.

/ˈtrɒpəsfɪə/, U.S.

/ˈtroʊpəˌsfɪ(ə)r/,

/ˈtrɑpəˌsfɪ(ə)r/

Origin: Formed within English, by compounding. Etymons: tropo- comb. form, -sphere comb. form.

Etymology: < tropo- comb. form + -sphere comb. form. In sense 1 after French troposphère (1908 or earlier in La division de l'atmosphère en troposphère et stratosphère d'après les résultats de l'exploration de la haute atmosphére , the title of a paper read by Teisserenc de Bort at a conference in Germany; compare quot. 1909 at sense 1). The region is so called because meteorological changes occur in it. In sense 2 applied to the ocean as an analogical development from sense 1, originally after German Troposphäre in similar use (A Defant 1928, in Zeitschrift der Gesellschaft für Erdkunde (Sonderband) 470); compare stratosphere n. 3.

1. Meteorology. The lowest region of the atmosphere (below the stratosphere), marked by convection and a general decrease of temperature with increasing height. Cf. tropopause n.

1909 Monthly Weather Rev. 1908 (U.S.) 36 371/1 (heading) Director Teisserenc de Bort, of Paris: The division of the atmosphere into troposphere and stratosphere, as based on the results of the exploration of the upper air.

1922 Nature 2 Feb. 141/1 In the lower layer, called the troposphere, the atmospheric gases are kept well mixed up by winds and convection.

1982 New Scientist 21 Jan. 151/1 Dust in the troposphere, the lowest layer of the atmosphere, is soon washed out by rain.

2006 G. Pretor-Pinney Cloudspotter's Guide vii. 173 The movement of the falling crystals, as they are whipped by the winds high in the troposphere, is what gives Cirrus their distinctive, flossy formations.

2. Oceanography. The upper layer of the ocean in which the water temperature rapidly decreases as depth increases.
