Abstract
This article discusses the parameters of thunderstorm activity in the structure of tropical cyclones that had an impact on the Russian Far East in August 2016. The study shows in detail the change in the cloud mass and describes its structure during the lifetime of the most powerful tropical cyclone Lionrock (2016). It is shown that the density distribution of lightning discharges in the range of tropical cyclones (up to 1000 km), reaching the typhoon stage, is characterized by two local maxima. The distribution density of lightning discharges in the range of tropical cyclones that have reached a strong tropical storm is characterized by one maximum. The lifetime of thunderstorm cells that stand out is 40-50 minutes in average. Before the typhoon stage, the area of thunderstorm cells increased, and then, the number of cells as well as the intensity of discharges in the cell increased, but their lifetime and area decreased.
Highlights
The economy of any state significantly depends on weather conditions
Meteorological parameters, together with the spatio-temporal characteristics of thunderstorm areas identified in the structure of a tropical cyclone, make it possible to predict the degree of danger of a natural phenomenon
In the Far Eastern region of the country, data obtained by means of the international global network WWLLN are used to monitor thunderstorm activity [1-3]
Summary
The economy of any state significantly depends on weather conditions. Extreme sectors, such as floods and hurricanes, have a significant impact on various sectors of the economy. One of the reasons for the occurrence of such dangerous phenomena is tropical cyclones, which are almost always accompanied by powerful thunderstorms. Meteorological parameters, together with the spatio-temporal characteristics of thunderstorm areas identified in the structure of a tropical cyclone, make it possible to predict the degree of danger of a natural phenomenon. In August 2016, 5 tropical cyclones, which reached the territory of Russia at the stage of a collapsing cyclone, had the greatest influence on the Far East. Tropical cyclones Lionrock and Mindulle reached the typhoon stage with a wind speed of about 36 m/s. The maximum stage of development of tropical cyclones Omais, Conson and Chanthu is a strong tropical storm
