ATMOSPHERE-LITHOSPHERE INTERACTION ON THE EXAMPLE OF CYCLONE ACTIVITY IN KAMCHATKA IN JANUARY, 2002

The influence of cyclonic activity on atmosphere-lithosphere interaction was considered. We investigated
the connection of a trajectory of cyclone movement with meteorological values, the dynamics of VLF-radiation,
the radon flow into the atmosphere and intensity of the Earth atmospheric electric field (Ez EFA) at Paratunka
observatory. The trajectories of cyclone movement were constructed according to satellite images, and the di-
rection of cyclone movement and the distance relatively the observatory were determined on the VLF-radiation
data. Approaching to Kamchatka coast the electric fields of two close cyclones formed a dipole, its movement
in the form of a signal of a certain form reflected in the electric field Ez FEA. During further approaching of
the cyclones to the observatory the radon flow into the atmosphere increased by four times due to the pressure
fall and temperature growth, it resulted in the fall of Ez values at 200 V/m. The presented data indicate the
close atmosphere-lithosphere interaction for the considered case.
