The Mediterranean

The application of an advanced third generation wave model to the Mediterranean Sea is described. The model is based on the physical description of the wind wave evolution, avoiding any shortcoming in the estimate of the single terms that contribute to the energy budget. The capability of the model to respond to any meteorological situation is illustrated by applying it to a severe storm occurred in January 1987. The results show that the crucial point for the final accuracy lies in the correct evaluation of the wind field.

Field Errors

To estimate uncertainties in wave forecast and hindcasts, computations have been carried out for a location in the Mediterranean Sea using three different analyses of one historic wind field. These computations involve a systematic sensitivity analysis and estimated wind field errors. This technique enables a wave modeler to estimate such uncertainties in other forecasts and hindcasts if only one wind analysis is available.

Transient Wave

This paper proposes new frequency dependence for the empirical formulas presently used to determine wave energy dissipation in ocean wave models. Using an energy focusing technique, several unidirectional transient wave trains were generated. Each of the transient wave train contained an isolated plunging or spilling breaker. By comparing the energy spectra of free-wave components before and after breaker it was found that: 1)the energy loss as function of frequency is almost exclusively from wave components at frequencies higher than the spectral peak frequency; 2)although the energy density of the wave components near the peak frequency are the largest, they do not significantly gain or lose energy after breaking; and 3)wave components of frequencies significantly below or near the peak frequency gain a small portion (about 12%) of energy lost by the high-frequency waves. The empirical formulas presently used to determine white-capping dissipation (Komen et al. 1994; Tolman and Chalikov 1996; Booij 1999) do not agree with the above spectral distribution of energy dissipation. Analysis of the dissipation distribution obtained by Meza et al. (2000), suggest that the dependence of the dissipation rate on the frequency should be described by, (ωωp)(1−(ωωp)E(ω), where ω is the wave frequency, ωp is the spectral peak frequency and E(ω) is the energy density spectrum. An energy dissipation source function with such a frequency dependence is being implemented and tested in a third generation wind wave model.

Mediterranean And Black Seas

<p>Reliable wave forecasts and hindcasts, together with long-term statistical analysis of extreme conditions, are of utmost importance for monitoring marine areas. Indeed, there is general consensus that high-quality predictions of extreme events during marine storms can substantially contribute to avoiding or minimizing human and material damage, especially in busy waterways such as the Mediterranean and Black Seas. So far, however, the wave climate characterization (average and anomaly relative to the average) has focused on the bulk characterization of the significant wave height H<sub>s</sub>, and it has lacked a description of the individual waves, such as the maximum ones that may occur at a given location in the sea. To fill this gap, we provide the intensity and geographical distribution of the maximum waves in the Mediterranean and Black Seas over 27 years (1993-2019), by representing the average annual (1993-2018) and anomaly for 2019 relative to the average of the 99th percentile of the expected maximum wave height H<sub>m</sub> and crest height C<sub>m</sub>. The analysis combines wave model hindcasts available through CMEMS model setup and the wave model WAVEWATCH III®, both forced with ECMWF ERA5 reanalysis winds. Results show that in 2019 maximum waves were smaller than usual in the Black Sea (anomalies of H<sub>m</sub> up to -1.5 m), while in the Mediterranean Sea a markedly positive anomaly (+2.5 m for H<sub>m</sub>) was found in the southern part of the basin. The peculiar 2019 configuration seems to be caused by a widespread atmospheric stability over the Black Sea and by depressions that rapidly passed over the Mediterranean Sea.</p>

Surface Wind Field

Sea surface wind field is a basic parameter of marine dynamic process, Catastrophic Sea-state such as marine tropical storm and storm surge are all driven by marine wind, wave monitoring and prediction also need sea surface wind field. By combining the new generation of weather research and prediction model (WRF) and the third generation wave model (WAVEWATCHⅢ), establish an Atmospheric-Wave numerical prediction system. Developing sea surface wind field numerical forecast in East China Sea, it makes up the shortage of wind field data’s absence. By using the numerical prediction results, the wave model will provide accurate and reliable wave forecast products for Chinese shipping, ocean activities and military affairs.
