摘　　要：本文利用逐次滤波法分析北半球平流层气候异常变化。结果表明 ,北半球 10～ 2 0 km高空气候存在尺度为 2 0年左右的年代际变化 ,年代际变化对气候的方差贡献率达到 2 0 % ;火山活动能引起平流层较大幅度增温 ,对高空气候异常变化的方差贡献率超过了 2 0 % ;平流层高空气候异常变化还具有显著的 2 2年变化周期 ,分析是大气温度场对太阳磁场磁性周期 2 2年异常变化的响应 ,其方差贡献率达到 5 % ;海温场异常是北半球 10～ 2 0 km高空气候异常变化十分重要的影响因子 ,其影响程度达到总的异常变化的 9%。Based on the study with successive filter analysis in this paper, it shows that there exists inter decade variation of about 20 year's scale. Its contribution to variance can reach 20%. Volcano activity causes atmospheric temperature to increase greatly. Its contribution to the variance of upper climate anomaly is over 20%. The variation of stratospheric climate anomaly has also 22 year's period. It is a response of atmospheric temperature to the 22 year's period anomaly change of magnetism field of the Sun. The contribution to the variance can reach 5%. Sea temperature anomaly is a very important factor to the climate anomaly of 10～20 km high and its effect comes up to 9% of total anomaly variations.
