“…Nevertheless very similar values are found with respect to nearby points in the simulation domain. Similar results have been obtained by Lavagnini and Sempreviva (1993), who have analysed the horizontal components of the wind at the isobaric altitudes of 850, 700 and 500 h Pa extracted from the ECMWF database for the period from 30 August 1982 to 31 December 1990 over the rectangular area (the opposite vertices of which are 36.0 and 46.51N and 7.5 and 18.01E) whose right border overlaps with the left border of our simulation domain.…”

“…Despite the length of the period analyzed (which is too short to be considered of climatological relevance), these results may be considered the most accurate presently available that are based on sea surface wind data uniformly sampled across the Mediterranean area, and not on coastal reports or sparse ship reports (HMSO 1962;May 1982), or on atmospheric model simulations (Lavagnini et al 2005;Lavagnini and Sempreviva 1993). Also, one of the most common sources of climate data, the 40-yr ECMWF reanalysis (ERA-40) fields (Uppala et al 2005), cannot be used in the regional seas because of the toocoarse resolution (2.5°).…”

This paper investigates the mean spatial features of the winds in the Mediterranean and Black Seas using the wind fields observed by the SeaWinds scatterometer. Five years (2000-04) of data have been analyzed on annual and seasonal basis, with particular attention paid to the meso-and local scales. The fields show the existence of structured regional wind systems-in particular, the mistral in the western Mediterranean and the etesians in the Levantine Basin, which are characterized, respectively, by high wind variability and moderate steadiness and by low wind variability and high steadiness. Estimated seasonal mean wind stress fields show that the values falling in the top range 0.15 Ͻ Ͻ 0.20 N m Ϫ2 affect a large portion of the Mediterranean Basin in winter, in the belt extending from the Gulf of Lion up to the Levantine Basin and the northern Black Sea. In the other seasons, only few regions experience such high values of . The analysis of the wind vorticity shows and quantifies the main cyclonic and anticyclonic circulations, and the study of the joint features of wind stress and vorticity has identified the strongest and most persisting local-scale wind circulations produced by the interaction between the wind flow and the orography. They occur at the lee side of Sardinia-Corse and Crete-Rhodos Islands and persist in all seasons, with some seasonal variation in strength and extent. The areas affected by the orographic disturbances are characterized by high values of wind stress and by a structure of vorticity showing alternating areas of cyclonic and anticyclonic circulations, whose strength is comparable to those of the regional-scale cyclones.

Offshore wind climatology over the Mediterranean basin

To obtain the offshore wind climatology over the whole Mediterranean region, European Centre for Medium-range Weather Forecasts (ECMWF) 6-hourly wind data over a grid resolution of 0·5° ¥ 0·5° for a period of 24 years have been retrieved. Data sets at 850 and 700 hPa pressure levels and 10 m above the surface were downloaded. For each grid point, mean wind speeds and Weibull probability density function parameters have been computed. As the wind field of ECMWF at 10 m is less accurate near the coast and in narrow basins, e.g. the Adriatic Sea, owing to the size of the mesh and land–sea mask smoothness, these statistics have been corrected, for each grid point, with the statistics produced using 2 year runs of a limited-area model with a grid size of 10 km. Results have been compared with experimental data from buoys, islands and ships in various regions of the basin.Maps of mean wind speeds and Weibull parameters are shown here for the whole Mediterranean Sea to illustrate these results
