摘要：

本文利用昭和基地 (6 9°0 0′ S,3 9°3 5′ E) 1 982～ 1 987年的臭氧总量的探空资料 ,着重分析了1 987年南极昭和站极夜期间臭氧含量变化与 5 0 h Pa风速、气温及变温的关系。发现在极夜期间 ,臭氧含量与 5 0 h Pa风速存在较好的相关性。根据热成风原理 ,计算了极夜期间的温度平流项 ,发现臭氧含量与 5 0 h Pa温度平流也存在一定的相关性 ,变温 ΔT的变化主要是由温度平流引起的。平流层臭氧只具有微弱的加热效应

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.
