Estimation of heat fluxes at the ocean-atmosphere interface in the south-western part of the Baltic Sea (2003—2016)

Based hydrometeorological data of the MARNET monitoring network, with the sampling interval of 1-hour, from 2003—2016, provided by the German Oceanographic Data Centre (BSH / DOD (M41)), the contributions of the irregular daily variability, the regular daily variability, the synoptic variability, the irregular intra-annual variability, the regular seasonal variability and the interannual component in the total temporal variability of the sensible and latent heat fluxes were estimated. The intra-annual and inter-annual variability of the specific contribution of the daily component of the sensible and latent heat fluxes are computed. It is shown that the structure of time variations of the fluxes in the southern part of the Baltic Sea depends on both, the station location and the nature of the flux itself.
