南极臭氧洞对全球大气辐射加热场影响的数值模拟研究

为了探讨南极臭氧洞对全球气候的影响状况，我们用IAP_9层全球大气环流模式进行了南极臭氧洞气候效应的数值试验。本文分析了本次试验中南极臭氧洞引起的大气辐射加热场的变化，结果表明，南半球高纬和极地平流层臭氧含量的严重减少，不仅影响该地的大气辐射加热场，同时也使北半球平流层大气的辐射加热场发生改变。虽然对流层中层所受影响较少，但对流层下层南北半球的大气总辐射加热率的变化却相当明显，这些影响将使全球大气温度场产生明显变化。

A Numerical Study of the Impact of Antarctic Ozone Hole on the Globally Atmospheric Radiative Heating Field

in order to study the impact of Antarctic Ozone Hole on the global climate, a numericalexperiment was carried out with IAP 9L AGCM. This paper emphasizes on the radiative heating fieldaffected by the Ozone Hole. Experiments show that the reduction of ozone in high latitude and polarregion of the Southern Hemisphere affected radiative heating fields not only the local but also of theNorthern Hemisphere Stratosphere. Although the total radiative heating field in the middle tropospherechanged little, it changed considerably in the lower troposphere of both Hemisphere. These effects madethe global temperature field change obviously.
