Abstract. Some results of simulation of the Black Sea circulation with consideration of forcing of different averaged wind types by using 3-D prognostic baroclinic model are presented. The results allow us to consider all depth of the sea basin consisting of some relatively homogeneous sub-layers. Within each of them general circulation processes practically do not change by depth, but essentially change from layer to layer. Such character of changeability interpreted by us as a steepness of the Black Sea general circulation takes place in majority cases of climatic atmospheric wind forcing. In the present paper results are analyzed on an example of forcing of January atmospheric cyclonic vortex with ~250 km diameter. Under such forcing the Ekman surface layer of ~12 m thickness is created. The cyclonic vortex formed in the east part of the Black Sea, which is Taylor-Proudman potential vortex with vertical cylindrical configuration, is described in detail. The vertical distribution of vortex characteristics are given in figures: Brunt-Väisälä frequency and Richardson number taken near the vortex wall with maximal velocity. The viable vortexes are characterized by introduced the universal Reynolds number Re•.
Let us proceed from stochastic wave equation of electric Under random unsteadiness of medium with weak spatial dispersion, on the basis of Dyson equation in Bourret approximation, dispersion relation is obtained connecting frequency and wave constant of electromagnetic radiation coherent wave with characteristic parameters of turbulent medium. Proceeding from the expression for effective refractive and absorption indices for Gaussian and Lane models, it has been shown that in both cases coherent waves attenuate on small-scale fluctuations of dielectric permittivity of inhomogeneous medium. * When considering the pulses in unsteady-state media, pole tracing L(k, w) = 0 must be carried out with causality principle taken into account.
A possibility of longitudinal and transverse electromagnetic wave excitation in randomly inhomogeneous non-stationary medium, modelled as a system of charged particle oscillators with own frequencies fluctuating in space and time, is examined in the present paper. An analytical expression for effective dielectric permittivity of the tensor is received for the case of an arbitrary correlation function of particle fluctuation frequency square, which allows to establish medium characteristic parameters. A possibility of attenuation or growing of waves generated in the medium under consideration is investigated.
