Creative works

  1. Studying the nature of high-latitude magnetic disturbances and founding the close relation between the polar cap magnetic activity and interplanetary electric field affecting the magnetosphere. Invention and putting into practice the polar cap magnetic activity PC index, as indicator of energy that enters into the magnetosphere during solar wind-magnetosphere coupling. Elaboration of methods for monitoring and nowcasting the space weather and magnetosphere state by means of the ground-based PC index.
  2. Founding the close relationships between the prolonged impact of intense solar wind on magnetosphere and such abnormal atmospheric processes, occurring in the winter Antarctica, as acceleration of the air masses descending into the lower atmosphere from the troposphere and formation of cloudiness above the Antarctic Ridge. These processes led to the sudden warming in the surface atmosphere and sharp increase of the atmospheric pressure in the near-pole region, the latter gives rise to the katabatic wind strengthening above the entire Antarctica and decay the circumpolar vortex about the periphery of the Antarctic continent. As result, the Antarctic cold air masses invade to the Southern ocean and the regular relationships between the sea level pressure fluctuations in the Southeast Pacific high and the North Australian-Indonesian low collapses with providing conditions for the El-Ni?o formation.
  3. Concept of the gravitation field variations as one of the important factors controlling the rhythmic of the biochemical processes.
