Abstract
The response of the thermobaric characteristics of the high-latitude troposphere to short-term events attributed to solar activity (solar cosmic rays and geomagnetic storms) has been investigated. The spatial manifestation of these disturbances in the troposphere is shown to be of a “focal” character. It is found that the manifestation is most evident in the cold period and depends on the properties of the underlying surface (land, ocean). The properties of the variations of the troposphere air temperature in the manifestation “foci” on the standard isobaric surfaces, as well as the variations of the altitude profile of temperature and the long-wave radiation flux at the upper boundary of the atmosphere, have been considered. The variations of the heat content of the high-latitude troposphere after solar flares have been analyzed. The variation of the thermobaric field is shown to be accompanied by the rearrangement of circulation forms in moderate and polar latitudes. The revealed properties are completely explained within the mechanism proposed here for the solar activity effect on the climatic characteristics of the troposphere.
