The stratosphere is extremely dry, due to its extremely cold temperatures. The coldest part between the troposphere and the stratosphere is called the tropopause, which blocks water from entering the ...

The coldest part between the troposphere and the stratosphere is called the tropopause, which blocks water from entering the stratosphere. There are many more features that make the stratosphere ...

Therefore, K-H instability related to tropopause folding is the main mechanism causing this aircraft turbulence. where z is the vertical direction, u and v are the zonal and meridional wind components ...
