Air-sea interaction on different time scales

This research is primarily funded by the Ministry for Education and Science of Russian Federation, Russian Foundation for Basic Research and Russian Academy of Science.

The major focus of the research is on the development of new VOS-based and blended global and regional ocean-atmosphere interaction fields, new parameterizations of air-sea energy exchanges and statistical methodologies for air-sea flux filed production. Most recently we developed global estimates of sampling errors of ocean-atmosphere fluxes over the World Ocean (Gulev et al. 2006a,b) and a new method which allows for the reconstruction of long-term air-sea interaction time series using limited data (Belyaev and Gulev 2006).

For the development of new parameterizations of air-sea short-wave and long-wave radiation fluxes we undertake in-situ measurements of surface radiative fluxes under the MORE (Meridional Oceanic Radiative Experiment). MORE is a joint initiative of IORAS and the Leibniz Institute of Marine Sciences at the University of Kiel (IFM-GEOMAR) with some contributions from the UK Met Office and the Meteorological Institute of the University of Bonn. MORE is set up to conduct long-term, high quality measurements of surface parameters and fluxes in the Atlantic Ocean with a particular emphasis on short wave (SW) and long-wave (LW) radiation fluxes. These are needed for proper quantification of the global ocean heat balance.

Under this research we develop numerous comparative studies of global and regional air-sea flux fields and flux-related parameters. Recently in co-operation with LEGI (Grenoble) different Global Ocean precipitation data were intercompared for the Global Ocean (Beranger et al. 2006). Comparison of global cloud cover from NCEP-NCAR reanalysis and VOS data was performed together with IFM-GEOMAR (Kiel).
