Abstract

This article investigates the spatial and temporal structures of the monthly mean vorticity fields omega(-sc) and omega(-e) over the Mediterranean Basin, derived respectively from satellite scatterometers and ECMWF global atmospheric model (T799) wind fields from February 2006 to January 2010. Statistics show a mean difference between omega(-sc) and omega(-e) over the whole Mediterranean Sea (relative bias Delta(omega) over bar) of 0.108x10(-5) s(-1). Furthermore, both the cyclonic and the anticyclonic components of omega(-sc) are stronger than those of omega(-e). The analysis of the spatial features of omega(-sc) and omega(-e) shows that the greatest discrepancies occur along coasts and in the Adriatic Sea, due to the ability of omega(-sc) to describe vorticity features smaller than about 6.9x10(3) km(2), roughly corresponding to square areas of side 83 km or circular areas of radius 46 km, that are not present in omega(-e), given the effective spatial resolution of the model. The temporal features of omega(-sc) and omega(-e) have shown a substantially similar trend in anticyclonic and a deep difference in cyclonic circulations, again related to the limited ability of omega(-e) to describe small-scale vorticity patches as the main source of the differences. Local characterization of omega(-sc) and omega(-)e, along six transects across areas where the wind vorticity features are well known, has confirmed the results of substantial similarity of omega(-sc) and omega(-e) at spatial scales larger than 100 km or so and remarkable differences in those regions, such as the Adriatic and Crete seas, affected by vorticity variability at smaller scales.
