,respectively); Canary--6; and Mediterranean Sea--7. Statistical analysis was performed using measurements of r~ at the wavelength 0.552 #m only. Characteristics of measurements in this channel are presented in Table 1 1. Figures 6a-g, respectively, provide frequency of occurrence information about ro~.ss within each of theabove-mentioned regions. The main conclusions areas follows.TABLE I 1.

and the Rayleigh model for the probability distributions of wave heights, he concluded that in cases where the wave height was greater than twice the significant wave height, the wave would be considered abnormal. The value of this ratio, which was later called the abnormality or amplification index (AI), is thus related to the duration of a sea state and a probability level, although there is no strong reason why 2.0 was chosen instead, for example, of 1.9, 2.1, or a similar number. In fact

are weak, for example, the western Mediterranean Sea ( Garcia-Gorriz et al. 2003 ). However, to allow for the complex patterns of current variations frequently encountered in shallow seas, higher-order polynomials or a large number of other spatial basis functions are required. A poor choice of complex basis functions can result in an ill-conditioned least squares problem, causing spurious oscillations in areas where data coverage is poor and making accurate separation of two or more tidal

. This dataset contains model data and simultaneous observations and it is applied to the significant wave height dataset of the 40-yr European Centre for Medium-Range Weather Forecasts Re-Analysis (ERA-40). Cavaleri and Sclavo (2006) made use of the overall information on models, buoys, and satellite to obtain calibrated decadal time series at a large number of points, distributed at 0.5° intervals in the Mediterranean Sea. These two approaches are applied on a point-to-point basis without

for the relatively large temperature differences in the North Atlantic, and that regional differences may play a role (see above). It is noted that the region where the largest temperature differences occur coincides quite well with the region where “meddies” (Mediterranean salt lenses), carrying the relatively salty and warm water originating in the Mediterranean Sea, are found (e.g., Armi and Zenk 1984 ; Käse and Zenk 1987 ; Sparrow et al. 2002 ). This gives rise to relatively large
