Abstract

A one-speed Boltzmann transport theory, with diffusion approximations, is applied to study the radiative transfer properties of lightning in optically thick thunder clouds. The cloud is modeled in terms of spherical geometry and studies on the effects of multiple scattering are considered. Mathematically, the cloud is composed of a homogeneous distribution of spherical water droplets. Computationally, the cloud is treated as a nuclear reactor, with photons replaced by neutrons. Diffusion techniques common in nuclear reactor analyses are applied as in [1]. Relevant numerical techniques will be used to simulate the Cloud Results for the obtained intensity distribution will be compared to those obtained in [1].
