The wind/wave climatology for the Arctic Seas will be developed based on altimeter observations. It will have a major scientific and applied significance as presently there is no reference climatology for this region of the ocean available. The new versions of wave models for the Beaufort and Chukchi Seas will include new physics that is already under development, and the novel physics presentl...

A field experimental study of the spectral balance of the source terms for wind-generated waves in finite-depth water was carried out in Lake George, Australia. The measurements were made from a shore-connected platform at varying water depths from 1.2 m down to 20 cm. Wind conditions and the geometry of the lake were such that fetch-limited conditions with fetches ranging from approximately 10...

methods to derive wind speed and the sea state from Synthetic Aperture Radar (SAR) satellite data are presented and applied for use in high resolution numerical modeling for coastal application. The new radar satellite TerraSAR-X (TS-X) images the sea surface with a high resolution up to 1m. So not only the wind field and integrated sea state parameters but also individual ocean waves with wave...

Offshore wind energy capitalizes on the higher and less turbulent wind speeds at sea. To enable deployment of wind turbines in deep-water locations, structures are being explored, where wind turbines are placed on a floating platform. This combined structure presents a new control problem, due to the partly unconstrained movement of the platform and ocean wave excitation. If this additional com...

A first geophysical validation of the ASAR Wave Mode Level 2 product is performed using ASAR Wave Mode data acquired during May 2002, which have been co-located with ECMWF WAM spectra and wind speed data. First calibration results and a comparison of wind speed and wave spectral parameters are presented and discussed. The performance of the product is as expected, with very good agreement in te...

Within the High Resolution Air-Sea Interaction (HiRes) DRI the Center for Maritime Research and Experimentation (CMRE), former NATO Undersea Research Center, will develop and validate methodologies to retrieve wind field parameters from X-band marine radars. The main parameters are the mean surface wind vector; the high-resolution wind field, as well as wind gusts in vicinity of the measurement...

The wind wave regime of Tallinn Bay, Gulf of Finland, is analysed with the use of a simplified method of long-term computations of wave fields based on a high-resolution nested WAM model and Kalbådagrund (1991–2000) wind data. The distributions of probabilities for wave heights, annual and seasonal mean wave heights, density of wave energy and its flux (wave power), and 1-year return wave heigh...

in this study, the capabilities of wawewatch-iii and mike21-sw for predicting the characteristics ofwind-generated waves in hormuz strait are evaluated. the numerical models have been set up using input data including gfs wind with 5° spatial resolution and 6 hours time intervals, along with the etopo1 bathymetry data with 2 arc-minute spatial resolutions. the results of the two model simulatio...

We investigate tropical cyclone wind and storm surge damage reduction for five areas along the Miami-Dade County coastline either by hardening buildings or by the hypothetical application of wind-wave pumps to modify storms. We calculate surge height and wind speed as functions of return period and sea surface temperature reduction by wind-wave pumps. We then estimate costs and economic losses ...

The authors use a coupled atmosphere-ocean-wave model (SWAN) to simulate winds in a particular region on the continental shelf in the Mediterranean Sea. After showing that the model does a good job in reproducing the observed wind and wave patters, the authors use different parameterizations for the atmospheric bottom roughness length: in one case it depends on wind intensity ("uncoupled" simul...
