Related to tropopause: stratosphere

(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 Poles
trop•o•pause(ˈtrɒp əˌpɔz, ˈtroʊ pə-)
the boundary, or transitional layer, between the troposphere and the stratosphere.
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.
The 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.
the zone between the troposphere and the stratosphere where the temperature remains relatively constant above a given point on earth.See also: Atmosphere
The thin layer of the atmosphere, about 3 mi (5km) thick, that lies between the troposphere and the stratosphere.
