Correlation between atmospheric circulation processes over the northern hemisphere and parameter of solar variability during 1899–2003

The Northern Hemisphere atmospheric circulation processes response to magnetosphere disturbance has been revealed. The time-series of cases of alternations of circulation patterns for the period 1899–2003 has been correlated with time-sequence of geomagnetic disturbances parameter – ‘aa’ index. The negative correlations between the time-series of deviations of inter annual index ‘aa’ from the linear trend and deviations of cases of circulation patterns alternations from the proper linear trend was established over the period of 105 years.
