Abstract. The dependence of the dispersion of the upwind and crosswind components of sea surface slopes and their anisotropy of the slopes on the range of waves that create them is analyzed. We consider a range with a changing boundary, from the the longest wind waves and/or swell to the to wavelengths λ0. We used data from radio and optical sensing, as well as in situ measurements (measurements by laser slopemeters, wave gauge, and wave buoys). Approximations of the dependence of the dispersion and anisotropy coefficient of the wave field on the parameter λ0 are constructed for the upwind and crosswind components of the slopes. It is shown that the estimation of the anisotropy coefficient obtained in the framework of the well-known Cox-Munk model, which is widely used in applications related to the reflection of electromagnetic waves from the sea surface, is not consistent with the estimates of this coefficient calculated from in situ measurements and from sea surface sounding data in the radio range.
Key words: sea surface, slopes, remote sensing, Cox-Munk model.
