| Abstract: | We consider some peculiarities of the behavior of thermal and radio thermal (microwave radiation) characteristics of the atmosphere during prestorm situations in water areas monitored directly and remotely. The objects of research are (a) a region of the SMKF1 station (Sombrero Key) in the Florida Straight in August 2005 and (b) Golubaya Bay in the Black Sea (Gelendzhik, the territory of the Southern Branch of the Shirshov Institute of Oceanology, Russian Academy of Sciences) in September 2010, several days before an intensive storm. Using meteorological and satellite microwave radiometric data, we have studied some common and specific features in the behavior of surface air temperature and humidity, surface fluxes of sensible and latent heat, total heat and water vapor content of the atmosphere, and microwave radiation characteristics of the “water surface-atmosphere” system during time periods preceding the approach of Hurricane Katrina to the region of SMKF1 and development of the sea storm near the Golubaya Bay. In both cases the effect of the accumulation of the latent heat of water vapor in the atmosphere was observed during the prestorm periods (of several days). |
