中文摘要：

本文根据全球高空10 hPa位势高度距平场EOF分析得知,存在于地面层大气中的南北向涛动现象~北极高空大气涛动和南极涛动,在高空大气中更为清楚,而且这种高空南北向涛动现象是波及全球的;存在于地面层大气中著名的纬向涛动现象~南方涛动（Southern Oscillation,SO）和北方涛动（North Oscillation,NO）,在高空大气中则变得不甚清楚.表征北极高空大气涛动的第一模态与表征南极涛动的第二模态的方差贡献率分别为41.47%和27.04%,二者累积方差贡献率达到68.51%,构成了平流层高空大气年代际振荡的主要形式;另外还存在两半球对称性中高纬度南极涛动模态和两半球不对称性中高纬度南极涛动模态,是高空大气中出现概率比较小的振荡形式.谱分析表明,无论北极高空大气涛动模态、南极涛动模态还是中高纬度纬向涛动模态,都存在与太阳磁场磁性指数相一致的22年准周期变化以及与太阳黑子相对数相一致的11年准周期变化;采用逐次滤波法的滤波分析和对比分析表明,高空大气涛动现象的重要影响因子乃太阳活动,其中太阳磁场的大幅度涨落及其磁性变化是主要因素,太阳黑子相对数的变化为次要因素.

英文摘要：

Based on EOF analysis of global geo potential height anomaly （GHA） field at 10 hPa level, the Arctic Oscillation （AO） and the Antarctic Oscillation （AAO） can be detected AO or AAO also has its global featur. The zonal oscillations the Southern Oscillation （SO） and the Northerm Oscillation （NO） in the atmospheric surface layer be- come less clear in the upper air. The first mode （AO mode, abbreviated as AOM hereafter） and second mode （AAO mode, abbreviated as AAOM hereafter） respectively have 41.47% and 27.04% of the variance contribution. The cumulative variance contribution of the first two modes reaches 68.51%. These two modes are the main components for the inter decadal or the decadal oscillation in the stratosphere. In addition, there still exist two kinds of oscillation patterns with less probability, namely the symmetric Antarctic oscillation pattern at mid-high latitudes and the asym- metric Antarctic oscillation pattern. Spectral analysis shows that the AOM and AAOM all have a spectral peak for 22- year＇s period, consistent with the periodic variations of the solar magnetic field and a peak for 11-year＇s period, consistent with the period of the numbers of sunspots. Step filter analysis shows that the influential factor for the upper atmospheric oscillation is the solar activity. The fluctuation of the solar magnetic field is the most influential factor and then variation of the sunspot number comes to the second factor.
