Subject: 1.1) What is the stratosphere?
The stratosphere extends from about 15 km to 50 km. In the
stratosphere temperature _increases_ with altitude, due to the
absorption of UV light by oxygen and ozone. This creates a global
inversion layer which impedes vertical motion into and within
the stratosphere - since warmer air lies above colder air, convection
is inhibited. The word stratosphere is related to the word
stratification or layering.
The stratosphere is often compared to the troposphere, which is
the atmosphere below about 15 km. The boundary - called the
tropopause - between these regions is quite sharp, but its
precise location varies between ~9 and ~18 km, depending upon
latitude and season. The prefix tropo refers to change: the
troposphere is the part of the atmosphere in which weather occurs.
This results in rapid mixing of tropospheric air.
[Wayne] [Wallace and Hobbs]
Above the stratosphere lie the mesosphere, ranging from ~50 to
~100 km, in which temperature decreases with altitude; the
thermosphere, ~100-400 km, in which temperature increases
with altitude again, and the exosphere, beyond ~400 km, which
