摘要
Three types of data were combined together to observe the evolution of the thunderstorm at the Straits of Malacca. The first data is a collection of electric field waveforms that where captured and analyzed to obtain the flash rates. Radar images from weather radar were observed in terms of their reflectivity value and cross section to locate the active regions of a thunderstorm. Next, a lightning detection system of World Wide Lightning Location Network (WLLN) capable of capturing lightning strike locations in latitudes and longitudes where used together with all the data to observe the if lightning are present at the active region. Upon overlaying the data, an observed cloud be found that the region with high reflective value (55-60 dBz) denoted with red color, have high concentration of lightning strike from WWLLN. Combination of data will help us understand further on the behavior of the thunderstorm.
