Abstract
The detail analysis of the aerological data from Vostok station (Antarctica) for 1978–1992 made it possible to find the dramatic changes of the troposphere temperature influenced by strong fluctuations of the interplanetary electric field E SW. The warming is observed at ground level and cooling at h>10 km if the electric field of dawn–dusk direction is enhanced (when interplanetary magnetic field Δ B Z <0). The opposite deviation of the atmospheric temperatures (cooling at the ground level and warming at h>10 km) is observed if the dawn–dusk electric field decreases (when Δ B Z >0). There is a linear relationship between the value of Δ E SW and ground temperature at Vostok station: the larger is leap in the E SW the stronger is temperature deviation. The effect reaches maximum within one day and is damped equally quickly. The temperature deviations occur not only while passing the front of the interplanetary shocks but while crossing the layers of interaction between the quasi-stationary slow and fast solar wind fluxes those are not accompanied by the cosmic ray variations at all. The appropriate response to the E SW changes is observed in tropospheric pressure and wind as well. It is suggested that the interplanetary electric field influences the katabatic system of atmospheric circulation, typical of the ice dome in winter Antarctic.
