tropopause
tro·po·pause T0380500 (trō′pə-pôz′, trŏp′ə-)n. The boundary between the troposphere and the stratosphere varying in altitude from approximately 8 kilometers (5 miles) at the poles to approximately 18 kilometers (11 miles) at the equator.tropopause (ˈtrɒpəˌpɔːz) n (Physical Geography) meteorol the plane of discontinuity between the troposphere and the stratosphere, characterized by a sharp change in the lapse rate and varying in altitude from about 18 km (11 miles) above the equator to 6 km (4 miles) at the Polestrop•o•pause (ˈtrɒp əˌpɔz, ˈtroʊ pə-)
n. the boundary, or transitional layer, between the troposphere and the stratosphere. [1915–20] tro·po·pause (trō′pə-pôz′, trŏp′ə-pôz′) The boundary between the upper troposphere and the lower stratosphere, varying in altitude from about 5 miles (8 kilometers) at the poles to 11 miles (17.7 kilometers) at the equator.tropopauseThe transition zone between the stratosphere and the troposphere. The tropopause normally occurs at an altitude of about 25,000 to 45,000 feet (8 to 15 kilometers) in polar and temperate zones, and at 55,000 feet (20 kilometers) in the tropics.tropopausethe zone between the troposphere and the stratosphere where the temperature remains relatively constant above a given point on earth.See also: AtmospheretropopauseThe thin layer of the atmosphere, about 3 mi (5km) thick, that lies between the troposphere and the stratosphere.Thesaurus| Noun | 1. |  tropopause - the region of discontinuity between the troposphere and the stratospherelayer - a relatively thin sheetlike expanse or region lying over or under anothertroposphere - the lowest atmospheric layer; from 4 to 11 miles high (depending on latitude) |

In the tropopause the lapse rate decreases, and temperature inversions are frequently observed. The height of the upper boundary of the troposphere is usually taken as the height of the tropopause. The height of the tropopause depends on geographic latitude, and the tropopause is higher in summer than in winter. Moreover, the height of the tropopause also depends on cyclonic activity; that is, the tropopause is lower in cyclones and higher in anticyclones. Over certain regions the tropopause often breaks up and then reforms; in the subtropics, breaks in the tropopause are regularly observed as we move from temperate to tropical latitudes. These breaks are associated with powerful subtropical jet streams. tropopause[′trōp·ə‚pȯz] (meteorology) The boundary between the troposphere and stratosphere, usually characterized by an abrupt change of lapse rate; the change is in the direction of increased atmospheric stability from regions below to regions above the tropopause; its height varies from 9 to 12 miles (15 to 20 kilometers) in the tropics to about 6 miles (10 kilometers) in polar regions. tropopause The boundary region at the top of the troposphere. In this atmospheric layer, an increase in altitude is not accompanied by a corresponding decrease in temperature. It is the coldest level in the atmosphere. The height of the tropopause is not constant at all latitudes. Over the equatorial regions, it is located around the 50,000-ft level, whereas over the poles it is only about 25,000 ft high. In the middle latitudes, it is encountered at about 35,000 ft. In the tropopause, the temperature is colder over the equator than over the poles.MedicalSeeatmospheretropopause
