SUMMER STATISTICAL MODELS OF CLOUD CHARACTERISTICS OVER WESTERN SIBERIA ACCORDING TO MODIS DATA

Abstract

Summer statistical models of textural features and physical parameters for various cloud types over the northern and southern parts of Western Siberia are proposed. The MODIS satellite data obtained over the study region in June, July, and August from 2010 to 2019 are considered. The model was constructed by determining the distribution laws that describe fluctuations in the values of various cloud parameters based on the Kolmogorov-Smirnov test. The summer cloud classification, that includes 14 cloud types, is presented. A feature of constructing a statistical model of optical thickness for powerful towering vertical clouds is considered. Estimates of the mean and relative standard deviation are given for some parameters and all considered cloud types in the northern and southern parts of Western Siberia. The results of forming statistical models both for individual cloud levels and for all varieties in general are discussed. Promising areas of developing the present study are given.
