Wind-wave modelling aspects within complicate topography

Abstract

Abstract. Wave forecasting aspects for basins with complicate geomorphology, such as the Aegean Sea, are investigated through an intercomparison study. The efficiency of the available wind models (ECMWF, UKMO) to reproduce wind patterns over special basins, as well as three wave models incorporating different physics and characteristics (WAM, AUT, WACCAS), are tested for selected storm cases representing the typical wind situations over the basin. From the wave results, discussed in terms of time-series and statistical parameters, the crucial role is pointed out of the wind resolution and the reliability of the different wave models to estimate the wave climate in such a basin. The necessary grid resolution is also tested, while for a specific test case (December 1991) ERS-1 satellite data are compared with those of the model.

A biogeographical analysis of the tenebrionid beetles (Coleoptera, Tenebrionidae) of the island of Thasos in the context of the Aegean Islands (Greece)

“…Second, the island could be subject to colonization from the mainland by dispersal more than other islands. Winds in the Aegean strongly influence wave direction and force according to two major patterns (Christopoulos 1997): (1) in summer dry winds of northern sectors, from North to South, prevail; (2) in winter, the Aegean is the site of violent wind storms both from North to South and from South to North. In this context, according to the maps of Christopoulos (1997), Thasos appears mostly affected by winds, and therefore waves, from North to South.…”
