Vhf emissions prior to the onset of initial electric field changes of intracloud flashes

We present the observation of VHF impulses electric (E) field emissions found in two normal intracloud (IC) flashes accompanied by initial electric field changes (IECs) in a tropical thunderstorm. The data was collected on November 23 ^ rd, 2017 (within reversal distance) to our lightning sensor in...
