-Localization of lightning strike point (LSP) in the forest is modeled to mitigate the forest fire damage. Though forest fire ignited by lightning rarely happens, its damage on the forest is grievousness. Therefore, predicting accurate location of LSP becomes crucial in order to control the forest fire. In this paper, we proposed a new hybrid localization algorithm by combining the received signal strength (RSS) and the received signal strength ratio (RSSR) to improve the accuracy by mitigating the environmental effect of lightning strike location in the forest. The proposed hybrid algorithm employs antenna theory (AT) model of cloud-to-ground (CG) return stroke lightning channel to forecast the location of the lightning strike. The obtained results show that the proposed hybrid algorithm achieves better location accuracy compared to the existing RSS method for predicting the lightning strike location considering additive white Gaussian noise (AWGN) environment.

In this paper, a parallel finite difference time domain (FDTD) code is developed for the calculation of the horizontal electric field above ground for three distances of 2 Km, 5 Km and 10 Km from the return stroke channel. An electromagnetic model of lightning is adopted for the purpose of simulation. The obtained results are compared with those simulated by Cooray-Rubinstein formula (CR). The effect of ground's conductivity on the electric field value is also investigated. The results show that the accuracy of CR formula decreases as the ground's conductivity decreases or distance of observation point from the lightning channel becomes larger.

“…More recently published electromagnetic models include those of Miyazaki and Ishii [58], in which NEC-4 is employed, and of Bonyadi-Ram et al [59], in which inductive loading is used to reproduce variation of return-stroke speed with height. Two papers in this special issue are devoted to electromagnetic models: Baba and Rakov [60] and Moosavi et al [61].…”

Abstract-This review paper, prepared for this second special issue on lightning of the IEEE TRANSACTIONS ON ELECTROMAGNETIC COMPATIBILITY, summarizes major publications on lightning and lightning protection since the first special issue published in November 1998, i.e., during the last decade. The review is organized in the following five sections: lightning discharge-observations, lightning discharge-modeling, lightning occurrence characteristics/lightning locating systems, lightning electromagnetic pulse and lightning-induced effects, and protection against lightning-induced effects.
