Abstract
Average vertical profiles of zonal and meridional components of winds, and of temperatures as obtained from M-100 meteorological rocket soundings conducted at Molodezhnaya, Antarctica in January-February 1972 (southern summer) are compared with those of the corresponding ascents from Thumba, South India. The actual results are also compared with the Groves atmospheric model and the corresponding departures of the actuals from the Model are worked out. It is found that in the southern summer the polar tropopause and stratopause were about 27°C and 13°C warmer than the corresponding equatorial tropopause and stratopause, while the mesopause was about 25°C colder. At both the stations the zonal winds in the stratosphere were predominantly easterly in January with speed less than 50ms-1, and westerly in February with speed less than 35ms-1, while the meridional winds were variable. Zonal wind departures of the actuals from the Groves model were found to be in a range of about ±35ms-1, while the temperature departures were mostly negative by about 25°C.
