Decreasing density with increasing altitude |
|
It is turbulent compared to the tropopause |
Option -c
The troposphere is characterized by turbulent mixing and overturning. This turbulence results from uneven heating of the surface and the atmosphere. Temperature decreases with height in this layer. This temperature decrease is known as the environmental lapse rate and averages 6.5 ºC/km. This layer extends from the surface up to an average altitude of 11 km (Ahrens 10). This altitude can range as high as 16 km in the tropics to less than 9 km over the poles (Lutgens 19). This range is due to the temperature differences between the tropics and poles. The warm surface temperatures and turbulent mixing over the tropics help to push the troposphere's boundary upward (Lutgens 19).
The tropopause extends above the troposphere.
Temperature remains constant with height in this layer. Jet streams
flow through the tropopause where the latitudinal variations in
temperature are great.
