Abstract :
Two mechanisms of forming the upgoing microwave (MCW) radiation in the system ocean-atmosphere (SOA) at millimeter and centimeter wavelengths have been taken into account: a) vertical transfer of turbulent heat (water vapor) through the ocean-atmosphere interface layer (10-30 meters) as well as through the boundary layer of the atmosphere (0-1500 meters) and the layer of the atmosphere, which is free from the turbulence (1500-16000 meters); b) horizontal heat transfer caused by atmospheric circulation in these layers. At the first case the theoretical method of artificial excitation of the fluxes of sensible (latent) heat in the SOA is used: correlation between near-surface atmosphere temperature and humidity and natural MCW radiation of the SOA is analyzed during their relaxation; the relationships between spectral characteristics of MCW radiation and heat fluxes in the range of synoptic time scales are in the focus. The excitation-induced evolution of the SOA is accompanied by significant changes in the water surface temperature, as well as in temperature and humidity of atmospheric layer (ABL), i.e., parameters that make a critical contribution to the formation and transfer of vertical electromagnetic and thermal fluxes-this circumstance is a prerequisite for its joint analysis
