  • Frequency Analysis of Thunder Features 
    R Abeywardhana; M Fernando; U Sonnadara; V Cooray (ICLP, 2016)
    Acoustic signatures of thunder can be used in understanding some properties of lightning channels. Basic features of thunder signal are qualitatively classified as Peals, Claps and Rumble. In studies [1] and [4], attempts ...
  • Regular Pulse Trains in Chaotic pulse Bursts 
    R Abeywardhana; M Fernando; U Sonnadara; V Cooray (ICLP, 2016)
    Electric field pulse bursts generated by lightning flashes are considered as sources of high radio frequencies. In this study, an analysis of pulse bursts in electric field records of 30 negative cloud to ground lightning ...
  • Time derivative of Electric Field Radiation Generated by Compact Intra Cloud Discharges 
    R Abeywardhana; M Fernando; U Sonnadara; V Cooray (ICLP, 2016)
    Time derivatives of electric field radiation (dE/dt) generated by Narrow Bipolar Pulses (NBP) in two tropical thunderstorms are investigated and two types of pulse characteristic in dE/dt signal were identified. One ...
