摘　　要：目的对比研究南极大陆高空臭氧含量对全球平流层大气温度场的影响。方法应用改进后的CCM1(R15L12)模式,以国家气象中心1991年1月16日的全球客观分析资料为初始场,积分到1998年7月31日。结果平流层上、中、下部温度下降的趋势均较为明显,同时部分区域温度略有增高,这在北半球更为显著。结论整体而言臭氧减少可造成平流层各层的温度降低,从而影响到平流层的大气环流及输送过程。Aim To compare and research effects of the ozone content above antarctic continent on the stratospheric temperature field. Methods By employing improved NCAR CCM1 （R15L12） spectral model,two experiments are carried out respectively. The integral time is 7 years,and the global objectively analyzing data at 12（ GMT）on July 16,1991 is used as initial field. Results The temperature on every layer is descending obviously, but some parts＇ are rising a little, which is more obvious in Northern Hemisphere. Conclusion Results of the numerical experiments indicate that the decrease of upper air ozone above antarctic continent has important effects on the stratospheric temperature field.
