ANALYSIS OF THE BLACK SEA SURFACE CURRENTS RETRIEVED FROM SPACE IMAGERY

Variational assimilation of space imagery observations into a transport-diffusion model is applied to the study of surface currents in the Black Sea basin. The processing of NOAA-AVHRR observations allows retrieving surface currents with a spatial scale of one kilometer in areas of few hundred kilometers. The examples presented here show that surface currents induced by mesoscale features with typical spatial scale up to few kilometers are very intense. The current speed obtained by processing satellite imagery sometimes exceeds twice that retrieved from altimetry measurements, which assumes at least ten km spatial averaging.
