Abstract:With its electrical characteristics,lightning causes severe damages to electronics that densely installed and frequently used on ships.Therefore,lightning monitoring is an indispensable part of maritime meteorological support for ships at sea.Any mistakes and omissions in lightning warning will directly result in the failure of such support tasks with irrecoverable and heavy losses.This paper presents a more accurate and reliable support mode after researching lightning physics and analyzing the monitoring methods of Doppler weather radars and SAFIR3000 monitoring system,both of which are the most advanced lightning monitoring equipment in China.This mode has seen successful applications in the maritime meteorological support for ships at sea.
