    Abstract

    The cyclonic storms are associated with strong winds, rainfall, and thunderstorms generating strong lightning discharges. Tracking of thunderstorms and rapid intensification of cyclones are important challenges in weather forecasting in order to warn the potential threats to the communities. Our analysis of World-Wide Lightning Location Network (WWLLN) detected lightning data suggests that lightning activity is greatly enhanced in the rainbands with secondary maximum in the eyewall of a mature tropical cyclone. The movement of a March 2010 tropical cyclone in the South Pacific region and associated lightning activity in the eyewall and the rainbands are presented to demonstrate the potential of WWLLN data in timely forecasting of thunderstorms associated with cyclonic storms thus reducing the overall threat to the Pacific societies as well as to ocean shipping and airborne carrier services flying in and/or over the Southwest Pacific Ocean.
