Abstract
We present the observation of VHF and microwave radiation pulses associated with initial breakdown process of five negative cloud-to-ground (-CG) flashes from two tropical storms. The -CG flashes were detected within and beyond reversal distances with the locations of the first return stroke were less than 10 km. Out of five flashes, only one detected with initial electric field change (IEC) process. Both VHF and microwave pulses were detected before the first classic IB pulse and the first microwave pulses were found to lead the first VHF pulses ranging between 0.03 and 23.9 ?S. � 2021 IEEE.
