INTERANNUAL CHANGES OF UPPER STRATOSPHERIC TEMPERATURES BASED ON RECENT SATELLITE OBSERVATIONS
Interannual changes of zonal mean temperature in the upper stratosphere are investigated for the period from 1979 to 1986 with the aid of TIROS-N/NOAA satellite observations.

Summary: | Interannual changes of zonal mean temperature in the upper stratosphere are investigated for the period from 1979 to 1986 with the aid of TIROS-N/NOAA satellite observations. It is found that a systematic interannual change of the temperature with a maximum in 1980 and a minimum in 1985 is predominant in the upper stratospheric summer of the Northern Hemisphere. The magnitude of the difference between the maximum and minimum temperature is about 2 K at the 1 mb level. This interannual change seems to be in phase with sunspot number index and may be caused by the 11-year solar cycle. In the Southern Hemisphere, however, such a systematic interannual change is unclear even in the summer season of the upper stratosphere, which is probably related to irregular occurrence of final warmings. |
