Study of thunderstorm activity connection with weather system structures over the North-Western Pacific Ocean

摘要

Applying the data of VLF direction finder receiving station of IKIR FEB RAS, included into the World Wide Lightning Location Network (WWLLN), the paper investigates the relations of field characteristics of recorded lightning discharges in the north-western part of the Pacific ocean with field characteristics of weather formation meteorological elements, evaluated according to the data of Earth remote sounding from satellites. On the example of separate tropical cyclones (TC) for 2012-2013, the relation of lightning discharge frequency and density with spatial distribution of driving wind whirl is shown. TC structure evolution is traced in cloudiness fields, driving wind whirl, and lightning discharge distribution.
