The results of mathematical modeling, which demonstrate the response of the tem\-perature conditions in the atmosphere of the Northern Hemisphere to the changes of the solar activity are presented. The calculations were carried out with the help of the ECSib climatic model (ICM&MG of SB RAS). In the course of calculations, the influence of the solar activity was examined on the basis of the model accounting for the effects of the solar activityon the climatic features of the troposphere. According to this model, the intensification of the solar activity increases the difference of the electrical potential between the ionosphere and the Earth that leads to the subsequent vertical redistribution of the charged nuclei of condensations across the troposphere, changing of the water vapor state and formation of cloudiness. The resulting cloudiness changes the radiation balance. Analysis of the results has the emphasis on the troposphere response to helio-geophysical perturbations in high latitudes for the cold period. It is shown that this mechanism may affect the temperature conditions of the troposphere in high latitudes.
