Numerical simulation of scattered light polarization in a developing convective cloud for millimeter wavelengths

Abstract

The optical characteristics of scattered light polarization in a developing convective cloud for millimeter wavelengths are numerically studied using the convection jet model and Stokes parameters. The analysis revealed that the value of all polarization forms does not depend on the cloud droplet spectrum and wavelength in the lower layers of a convective cloud. As the cloud droplet size increases and the wavelength decreases, the polarizations of all forms vary greatly and may have several maxima. It is also demonstrated that the degree of partial polarization may make no sense in the Rayleigh region at the certain values of polarization parameters.
