| Summary: | Abstract. A strong thunderstorm front has passed over Kamchatka in August 2007. On August 27 strong thunderstorm discharges have been visually observed in Paratunka, Kamchatskiy krai. Visually observable thunderstorms are very rare in Kamchatka. This phenomenon is considered to occur 1-2 times a year. Moreover it is difficult to locate this phenomenon. In the region during thunderstorm formation and during its visual observation the registration of thunderstorm discharges was carried out by VLF-direction-finder in Paratunka. Hour dependence of thunderstorm discharges as well as azimuthal distribution is presented over whole period of the observation of thunderstorm activity. Comparison of direction-finding and meteorological characteristics was carried out. The analysis of thunderstorm dynamics according to the data of VLF radiation and meteorological parameters points to the fact that sudden change of wind direction entails the increase of quantity of thunderstorm discharges in a thunderstorm source. |
