The NASA link I posted has pictures.
That was quite interesting. Since those layers of the atmosphere (troposphere and stratosphere) do not readily mix, it would be interesting to see how that affect the climate. The stratosphere unlike the troposphere warms as you gain altitude. Humid air being more buoyant then dry air, that air ought to rise to the next boundary area. I may try to look at some stratospheric temperature data over the last year and a half.
