  • troposfääri ja stratosfääri vahekiht, milles troposfäärile iseloomulik temperatuurilangus väheneb, kaob või muutub vastupidiseks
  • the boundary between the troposphere and the stratosphere, where an abrupt change in lapse rate usually occurs
Good to know
  • Valdkond ICAO lisade põhjal loodud klassifikaatori järgi: Lennumeteoroloogia
  • Tropopausis väheneb temperatuurigradient järsult ja temperatuur võib ka tõusta. Tropopausi all või alumises osas on teatud kohtades õhujõud – jugavoolud, milles õhk võib liikuda mitusada km/h. Tropopaus võib-olla katkendlik (klimatoloogiliste frontide piirkonnas) või mitmekihiline. Tropopaus on iseloomulik vaid Maa atmosfäärile.

Usage examples
  • At the top of the troposphere is a boundary known as the tropopause, which traps moisture and the associated weather in the troposphere. The altitude of the tropopause varies with latitude and with the season of the year; therefore, it takes on an elliptical shape as opposed to round. Location of the tropopause is important because it is commonly associated with the location of the jet stream and possible clear air turbulence.
  • Meteorological information supplied to operators and flight crew members shall be up to date and include the following information, as agreed between the meteorological authority and the operators concerned: a) forecasts of: 1) upper wind and upper-air temperature; 2) upper-air humidity; 3) geopotential altitude of flight levels; 4) flight level and temperature of tropopause; ...
