Abstract: | on the ozone and aerological sounding data at Syowa Station (69° 00’S, 39°35’E), Antarctica during 1966—1979 and Lhasa Station
(39°40’N, 91°08’E), Tibetan Plateau during 1979—1983, the processes of temperature increase in spring over the Tibetan Plateau
and the Antarctica are compared in this paper, and the relationship between the increase of air temperature and variation
of total ozone and ozone partial pressure is analyzed. It is found that: (1) The process of temperature increase over the
Tibetan Plateau is quite different from that over the Antarctica in spring. This is a proof that the heating effects of their
ground surface on the atmosphere are of great difference; (2) Sudden increase of total ozone is always associated with sudden
warming in the stratosphere over the Antarctica, but sudden decrease of total ozone is associated with sudden warming in the
troposphere over the Tibetan Plateau in spring: and (3) There is a good positive correlation, with a correlation coefficient
of about 0.85, between the temperature increase and variation of ozone partial pressure in the stratosphere over the Antarctica
in spring. |
