PARAMETRIZATION OF THE PROCESSES OF INTERACTION OF THE ATMOSPHERE AND OCEAN
Obviously, without taking into account the characteristics of the interaction of the atmosphere and the ocean, it is impossible to successfully develop both atmospheric circulation modeling and the methods of long-term and long-term forecasting of weather and climate created on its basis. In the general problem of energy exchange between the ocean and the atmosphere, small-scale interaction occupies a special place, being the determining factor in the exchange of heat, momentum and moisture directly across the interface between interacting media. Therefore, over the past decades, the study of the interaction of the atmosphere and the ocean has turned from a small section of marine climatology into a key area in modeling the ocean-atmosphere system. To assess turbulent flows in this system, the Monin-Obukhov similarity theory, direct and indirect measurement methods are used. The information accumulated as a result of such experiments serves as the basis for constructing schemes for calculating the characteristics of local heat and mass transfer based on standard hydrometeorological measurements, and is also the basis for providing the boundary conditions necessary for combining atmospheric and oceanic circulation models. The report will provide an overview of measurement methods and indirect estimates of turbulent flows, as well as approaches to the development of parametrizations for calculating heat, moisture and momentum fluxes in the ocean-atmosphere system, and schemes of individual parameterizations are presented. An overview will be given of the results of complex experiments conducted with the aim of developing and verifying methods for calculating the parameters of the interaction of the atmosphere and the ocean. Particular attention will be paid to stormy and calm conditions, as well as the interaction of the atmosphere and the sea in coastal areas.
