Paper Abstract

This paper presents the results of investigations of mid-latitude upper atmosphere response to tropical cyclones, which were observed over the Northwest Pacific Ocean in September-October 2005. It is accepted that internal atmospheric waves (IAWs) are one of physical mechanisms of the interaction between the troposphere and ionosphere. It is also assumed that IAWs travel upward along oblique trajectories and manifest themselves in the upper atmosphere as traveling ionospheric disturbances (TIDs). Such TIDs can be registered at distances of some thousands of kilometers from the IAWs tropospheric source. To check up this hypothesis we have carried out statistical and harmonic analyses of data of the vertical sounding of the upper atmosphere in the East Siberian and Far Eastern regions of Russia, in the China and in the Australia. The disturbances, which most probably can be associated with cyclones, were picked out from variations of ionospheric F-region parameters: the increase of oscillation amplitude in the range of periods 1.5-6 h; essential deviation of F-region parameters from their medians.
