homopause

(turbopause)
(level of atmosphere up to which components are mixed)

Homopause (aka turbopause) is a term for the level of an atmosphere below which some components are mixed (by turbulence), and above which such mixing does not occur. Without the mixing, the constituents tend to be stratified, lighter with altitude. The atmosphere below the homopause is called the homosphere and that above is called the heterosphere. The Earth's homopause is 80-100 km above sea level, with its homosphere including the troposphere, stratosphere and more, generally including all of what we experience as weather.
