Abstract

The lightning channel is a rapidly evolving transient plasma that radiates intense electromagnetic (EM) fields and emits broadband optical radiation. This paper presents a theoretical and experimental investigation into the correlation between electromagnetic fields generated during lightning events and the corresponding optical spectra observed during various phases of the discharge. Using advanced EM field modelling and high-speed optical spectroscopy, we demonstrate that key plasma parameters such as temperature, electron density, and ionization state can be inferred from combined electromagnetic-optical datasets. This multidisciplinary analysis not only reveals the underlying physical characteristics of the lightning channel but also provides insights for future atmospheric diagnostics, lightning modelling, and protective technologies.
