Abstract:

In this paper, a major analysis on the total amount of ozone variation and its relation with the wind speed, temperature and the rate of temperature change at the 50 hPa height over Syowa Station in Antarctic during the polar night in 1987 is made by using the total amount of ozone and upper air data of Syowa Station from 1982 to 1987. We found that there is a quite good coherence between total amount of ozone and the wind speed at 50 hPa height during the polar night. According to the principle of thermal wind, we calculated the thermal advection during the polar night in 1987, we also found that there is a good coherence between total amount of ozone and the thermal advection at 50 hPa height, and found that the variatoin of temperature mainly caused by thermal advection. Stratospheric ozone only has the feeble heating air function.
