摘要：

When solving the problem of light scattering on ice crystals of cirrus clouds, two limiting cases can be distinguished: a model of ideal hexagonal particles and a model of randomly shaped particles. As already shown, the optical characteristics of particles that are closer to the real forms of atmospheric crystals are not go beyond these limiting cases. Before solving the problem of light scattering within the framework of the physical optics method, it is necessary to carry out a number of basic estimates. These estimates include the study of the convergence of the numerical solution on the number of iterations of the beam splitting algorithm and the number of spatial orientations of the particle during its averaging. The results of this study are presented in the report.
