Finite Element Analysis of the Mesosphere's Electromagnetic Response to Large Scale Lightning Associated with Sprites and other Transient Luminous Events

Abstract

In this research, a numerical investigation of high altitude sprites and other mesospheric Transient Luminous Events induced by lightning is presented. A Finite Element Model is created using equations based on a modified form of Maxwell’s equations and includes the effects of ionization on the upper atmosphere. Results will first be shown for standard models with constant ambient conductivity which will be verified based on prior research. A model will then be introduced which includes ionization effects altering the electron conductivity in a non-linear manner. These results will be compared to previously published research.
