Abstract

It is found that the year-to-year changes of the mean zonal winds in the SH winter and spring (August, September, and October) in the lower stratosphere have shown no clear trends during the period from 1980 to 1988, in contrast to the ozone depletion and temperature decline. However, surprisingly, there are apparent differences in the zonal wind comparison between the 1980s and the early 1970s. The differences in the Antarctic lower stratosphere in the winter and spring are evident in that the zonal winds poleward (equatorward) of 60°S become weaker (stronger) in the 1980s by over 10 m/s than in the early 1970s. On the other hand, the amplitudes of stationary waves of wavenumber 1 in the 1980s become weaker by about half of the amplitudes in the early 1970s. -from Authors
