What does that mean? For extra credit: explain the word tropopause.
Oh dear. Long subject & I don’t know if you are pulling my chain or not, but hey.
I’m a pilot and an instructor so I deal with WX on a regular bsis.
The tropopause is a boundary layer between the lower atmospehere (troposhere) and the upper atmoshere (stratosphere) where the air ceases to cool as you gain altitude, ie, the lapse rate ceases to be consistant.
here in florida it is close to 10 miles up and at the poles its about 4 miles up. cool air condenses and sinks, hot air rises, heance the Tropopause is higher at the equator than at the poles.
Harder to fly where there is no air...
