• Sommario/riassunto: The goal of this book is to provide the theory, mathematics and computational tools that are necessary to model each and every one of the processes associated with lightning discharges. This is essential information for a newcomer to the subject as well as for experienced scientists working in this field. Indeed, it is only through exercising various models and mathematical simulations that one can understand the basics mechanisms associated with the generation and interactions of the electric and magnetic fields of thunderclouds and lightning.
