Abstract

Analysis of microbaric variations and variations of the electric field during atmosphere strong disturbances were carried out on the base of the data of instrumental registrations obtained in the geophysical observatory "Mikhnevo" of the Institute of Geospheres Dynamics of the Russian Academy of Sciences (IGD RAS). It is shown the hurricanes and storms are accompanied by high-amplitude variations of acoustic and electrical fields. Amplitudes of variations of these fields increase in a several hours before front arrival. This fact in the aggregate with meteorological parameters could be considered as a predicted indication of approaching hurricane or storms. It is determined that thundery front arrival is forestalled by long period electric field variations, internal gravity waves and increased acoustic impedance. Regularities, which were determined resulting from investigations, could be raise of forecast reliability and efficiency.
