Abstract. Isentrope surfaces in the Southern Hemisphere stratosphere reveal that air
parcels undergo mesoscale temperature fluctuations that depend on latitude
and season. The largest temperature fluctuations occur at high latitude
winter, whereas the smallest fluctuations occur at high latitude summer. This
is the same pattern found for the Northern Hemisphere stratosphere. However,
the amplitude of the seasonal dependence in the Southern Hemisphere is only
37% of the Northern Hemisphere's seasonal amplitude.
