摘　　要：本文参照太阳黑子相对数特征建立了太阳黑子磁场磁性指数时间序列 .大气温度场谱分析结果显示 ,南北半球中纬度平流层和对流层大气温度场普遍存在 2 2年变化周期 .分析认为 ,大气温度场的 2 2年变化周期是太阳活动 2Based on the characteristics of the sunspot number, the time sequence of the magnetic index of the sunspot magnetic field is established in this paper. The analysis of the temperature field spectrum shows that in the air temperature field of the troposphere and stratosphere at the middle latitudes of northern and southern hemispheres there generally exist cycles with a 22 year period. The analysis also shows that the cycle of the air temperature field with the 22 year period is generated by the solar activity with the 22-year period.
