Findings

Quantitative agreement between calculated and observed parameters.

Model effectively incorporates wind-wave state effects.

Provides a method for estimating friction velocity and drift currents.

Abstract

A version of model is proposed, which is aimed for getting parameters of the atmospheric layer and upper water layer with account of the wind-wave state. The dynamics of the atmospheric boundary layer is realized in version of papers [1, 2], and the dynamics of the upper layer is realized in the framework of Ekman layers in the atmosphere and the sea [3]. In the latter case, the Kitaigorodskii [4, 5] approach was used for describing the dynamics of the air-water interface. The key parameters of the atmospheric layer and upper water layer (the friction velocity and the speed of drift currents) are calculated for typical wind-wave situations. Satisfactory quantitative agreement between calculated and traditionally observed values is shown.
