The Effects of Clouds on the Light Produced by Lightning

摘要: Abstract A Monte Carlo method has been used to simulate the transport of visible (0.45 μm) and near-infrared (0.87 photons which are produced by transient light sources, such as lightning, within cubic, spherical cylindrical clouds. Computations total absorption, fractions escape various cloud surfaces, flux density at surface, angular distributions given for source locations. The results show that absorption with point extended sources is negligible in less than 20% optical depths up 400. surfaces high when close surface; if a center cloud, these same there were no present all, except loss. Most discharges in-cloud portion cloud-to-ground flashes occur or above t...
