Structural Description of Geophysical Random Fields with Non-Gaussian Statistics

This article considers an approach to the describing random fields as a set of intense structures with random parameters. Such structures are observed both in optical fields propagating in inhomogeneous media and in fields of hydrodynamic origin, and they are formed because of the focusing of radiation or deformation of flows. Filtration methods and the evolution of such structures are discussed and different modes of structures-modes of periodic and stochastic oscillations-are described.
