stratopause Meteorol.|ˈstrætəʊpɔːz|
[f. stratosphere + pause n.]
The upper limit of the stratosphere, separating it from the mesosphere. (In current use at a greater height than formerly: cf. stratosphere 2.)
1950S. Chapman in Jrnl. Atmospheric & Terrestrial Physics I. 121 Taking stratosphere to denote the nearly isothermal region above the troposphere, its upper boundary, where the temperature first begins to increase upwards more rapidly than is common in the lower stratosphere, would be the stratopause. 1963Q. Jrnl. R. Meteorol. Soc. LXXXIX. 156 At its meeting in June 1962, the executive committee of the World Meteorological Organization passed a resolution on the terminology..for the high atmosphere. It is as follows:..(a) Stratosphere: Region (situated between the tropopause and stratopause) in which the temperature generally increases with height. (b) Stratopause: The top of the inversion layer in the upper stratosphere (usually around 50 to 55 km). 1979Jrnl. Atmospheric Sci. XXXVI. 1616/1 Large [meridional wind] oscillations are seen near the stratopause (∼ 50 km) with a period of about 2 days and an amplitude as large as 30 m s-1. |
