The lowest atmospheric layer; from 4 to 11 miles high (depending on latitude).
All the atmosphere below the stratosphere.
Lower part of the Earth’s atmosphere extending about 10.5 km/6.5 mi from the Earth’s surface, in which temperature decreases with height to about -60şC/-76şF except in local layers of temperature inversion. The tropopause is the upper boundary of the troposphere, above which the temperature increases slowly with height within the atmosphere. All of the Earth’s weather takes place within the troposphere. + prikaži više
