太阳磁场磁性指数异常变化对南北半球中纬度气候的影响

Based 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.
