Opis

We will show in this monograph some possibilities of using the potential of satellite passive microwave radiometric methods for the analysis of variations of heat and dynamic processes in the ocean atmosphere interface in a wide range of time scales from mesometeorogical (hours, daily) to seasonal (month) and multiyear (climatic) ones. The most essential mechanisms of intercommunication of natural microwave radiation of the system ocean atmosphere (SOA) with the vertical turbulence fluxes of sensible, latent heat, as well as the momentum at the boundary of the SOA are studied. We will consider the turbulence heat fluxes as the factors generated by the c- otic movements in the atmosphere, when every small individual part of air is moved irregularly. Here, one can observe a transfer of the energy from large-scale to sma- scales; the average distance between the air particles is increased with a time. Also, the potential of remote sensing the characteristics of heat and water adv- tion and their accumulation in the atmosphere boundary layer are demonstrated. In these studies, we mean mainly the middle and high latitudes of the North Atlantic, which are forming the weather conditions and climatic trends over Europe and European territories of the Russia."

Aimed at scientists using satellite microwave radiometry to study remote sensing of the heat and dynamic interaction between ocean and atmosphere, this text is a fully revised and expanded edition of the authors’ 2004 monograph "Intercorrelation between Natural Microwave Radiation of the Ocean-Atmosphere System and its Boundary Heat and Dynamic Interaction", previously published only in Russian.

The book describes different approaches to the analysis of heat and dynamic processes in the ocean-atmosphere interface with satellite passive radiometric observations of microwaves. It examines the feasibility of determining synoptic, seasonal and year-to-year variations of sensible, latent heat and momentum fluxes to a useful accuracy using the DMSP SSM/I data directly from the measured brightness temperatures.

In addition, the text considers the parameters of the ocean surface and the near surface atmosphere as they relate to the processes of the ocean-atmosphere heat and dynamic interaction. These processes can be analyzed from satellites using a variety of methods, including comparison of data of synchronous satellite passive microwave radiometric and direct oceanographic and meteorological measurements, and the modeling of their variations and analysis of interrelations at different time scales. The main results have been obtained by combining data from the vessel experiments NEWFOUEX-88, ATLANTEX-90 and the data of microwave radiometric measurements from the DMSP series of meteorological satellites.

At the same time as covering a key topic area with implications for global warming research, this text will also be useful to students who want to gain insight into the application of satellite microwave radiometric methods for studying the air-sea interaction.

Key themes: air-sea interaction, brightness temperature, heat and momentum surface fluxes, radiation models, satellite radiometry, ATLANTEX-90, NEWFOUEX-88
