The
amount of wave energy that moves up from the troposphere into the
lower stratosphere (roughly 17 to 30 km altitude) significantly affects the temperature, and therefore the
ozone depletion, at these altitudes, where the bulk of the
ozone layer is located.
Current research combines the climate and chemistry changes in the GISS model to predict future stratospheric
ozone amounts both over the polar regions and at
lower latitudes.
Using a computer model, they showed that weather conditions would have
lowered the
amount of
ozone over Antarctica anyways, and that the big hole was a result of winds from the tropics carrying less
ozone to the area than in the years before.
