Abstract
When fields of atmospheric parameters are statistically described, researchers usually proceed from the assumption that these fields are homogeneous and isotropic. Many one-dimensional models of correlation function approximants of these fields have been obtained based on the assumption on the statistical structure of the atmospheric parameter field. However, not all fields of atmospheric parameters can be considered homogeneous and isotropic. The anisotropy of the temperature and wind fields in the zonal and meridional directions has been studied and their anisotropy has been qualitatively estimated. The two-dimensional model for an approximant of the correlation function of the atmospheric parameter fields, taking into account the anisotropy effect in the zonal and meridional directions, has been proposed. The geopotential height of different isobaric surfaces has been calculated using an existent homogeneous model for correlation function approximant of atmospheric parameter fields and the proposed two-dimensional model. The values indicating that the interpolation accuracy increases when the proposed two-dimensional model for the correlation function approximant is used, since the morphology of atmospheric parameter fields is more adequately taken into account in the proposed model, have been obtained.
