Evaluation of the existence of initial breakdown process for cloud-to-ground flashes
In this paper, we are motivated to evaluate the existence of Initial Breakdown (IB) process in Cloud-to-Ground (CG) flashes of a tropical storm by using both broadband E-field and B-field antenna systems. It is important to note here that all previous studies were using only broadband E-field antenn...

In this paper, we are motivated to evaluate the existence of Initial Breakdown (IB) process in Cloud-to-Ground (CG) flashes of a tropical storm by using both broadband E-field and B-field antenna systems. It is important to note here that all previous studies were using only broadband E-field antenna system. In this study, the evaluation of existence of IB process was done based on both broadband E-field and B-field antenna systems. The data of lightning flashes were collected on June 3 rd 2016 by our station in Malacca, Malaysia. We analyzed 50 CG flashes from a tropical storm happened in Kuala Lumpur area. The data recorded by broadband E-field antenna system shows that 94% of CG flashes were preceded by IB process. On the other hand, by using B-field antenna system, all CG flashes have been observed to be preceded by IB process.
