Noun
tropopause (plural tropopauses)
The zone of transition between the troposphere and the stratosphere (approximately 13 kilometers). The tropopause normally occurs at an altitude of between 25,000 and 45,000 feet in polar and temperate zones. It occurs at 55,000 feet in the tropics.
Because the temperature in the tropopause and lower stratosphere is largely constant with increasing altitude, very little convection and its resultant turbulence occurs there. Source: Internet
Ethane and acetylene tend to condense in the colder lower part of stratosphere and tropopause (below 10 mBar level) forming haze layers, which may be partly responsible for the bland appearance of Uranus. Source: Internet
Measuring the temperature change with height through the troposphere and the stratosphere identifies the location of the tropopause. Source: Internet
The clouds are located in the tropopause and are arranged into bands of different latitudes, known as tropical regions. Source: Internet
The lowest temperature recorded in Uranus's tropopause is 49 K, making Uranus the coldest planet in the Solar System, colder than Neptune. Source: Internet
The temperatures in the coldest upper region of the troposphere (the tropopause ) actually vary in the range between 49 and 57 K depending on planetary latitude. Source: Internet
