Manifestation of isolated heliogeophysical disturbances in the high-latitude troposphere.
The results are presented of the research into the response of high-latitude troposphere climatic characte-ristics to isolated heliogeophysical disturbances (HGD) (solar cosmic rays, geomagnetic storms). It is shown that these disturbances are accompanied by regular changes of the thermobaric field dynamics. It has been found that the typical zonal transfer disturbance, which manifests itself in appearance «quiesce» of isolated moving structures, takes place after HGD. It is precisely these stationary regions which are of maximal troposphere response to HGD. It has been established that after heliogeophysical disturbances in the isolated high-latitude regions of the lower and middle troposphere, there can be observed a significant (up to 15°) temperature increase, while in the upper troposphere - its decrease. Heat content change in latitudes over 50° related to isolated HGD can reach several percents of the annual variation amplitude. The revealed regularities are totally explicable on the basis of the model and mechanism of the solar activity influence on the troposphere climatic characteristics previously suggested by the authors.
