Features of the local areas deep structure of on tropical cyclone movements trajectories

Abstract

Summary The results of studying the deep structure in local areas along the trajectories of tropical cyclones (TCs) movement in 2017 are presented. In four regions of TC activity, 56 local areas were examined along 5 trajectories of cyclone movement. Additionally, a survey of the central zones of 25 TCs, recorded by spacecraft, was carried out. Investigations on local areas of cyclones movement were carried out using frequency-resonance methods of satellite images processing. During the images processing of survey areas on the trajectories of cyclone movement, from the surface instrumental measurements were carried out in order to register responses (signals) at the frequencies of hydrogen and basalts. The results of processing images of the 81st local area indicate that the formation and movement of TCs occurs mainly along the areas of basalt volcanoes location, as well as basalt deposits in the upper part of the cross-section. The results of the conducted studies indicate the feasibility of using mobile methods of frequency-resonance processing of satellite images for predicting the places of formation and trajectories of the tropical cyclones.
