This research simulates one of the natural phenomena, the ocean wave. Our goal is to be able to simulate the ocean wave at real-time rate with the water surface interacting with objects. The wave in this research is calm and smooth caused by the force of the wind above the ocean surface. In order to make the simulation of the wave real-time, the implementation of the GPU and the multithreading ...

In this study, we proposed an empirical algorithm for significant wave height (SWH) retrieval from TerraSAR-X/TanDEM (TS-X/TD-X) X-band synthetic aperture radar (SAR) co-polarization (vertical-vertical (VV) and horizontal-horizontal (HH)) images. As the existing empirical algorithm at X-band, i.e., XWAVE, is applied for wave retrieval from HH-polarization TS-X/TD-X image, polarization ratio (PR...

Hourly and 12 km horizontal resolution wind fields simulated by the WRF model (Weather Research and Forecasting model) have been used to force the WAM model (WAve prediction Model), for a wave hindcast run in the southeastern Bay of Biscay. Three-hourly boundary conditions (defined by directional wave spectra) were provided by the WAVEWATCH III model, run by NOAA. The year 2009 was selected to ...

Internal gravity waves have an important effect on the large-scale circulation of the middle atmosphere, which is conditioned by the deposition of momentum due to their breaking. The propagation of gravity waves is influenced by the properties of the background wind. This thesis examines this influence: it uses stochastic techniques to study gravity wave propagation through a randomly fluctuati...

NCMRWF (National Centre for Medium Range Weather Forecast) winds assimilated with MSMR (Multi-channel Scanning Microwave Radiometer) winds are used as input to MIKE21 Offshore Spectral Wave model (OSW) which takes into account wind induced wave growth, non-linear wave-wave interaction, wave breaking, bottom friction and wave refraction. The model domain covers the north Indian Ocean, bounded by...

Mountain waves could be modified as the boundary layer varies between stable and convective. However case studies show mountain waves day and night, and above e.g. convective rolls with precipitation lines over mountains. VHF radar measurements of vertical wind (1990–2006) confirm a seasonal variation of mountain-wave amplitude, yet there is little diurnal variation of amplitude. Mountain-wave ...

Among field studies of wind-generated surface gravity waves on deep water, the case of a fetch limited wave growth is of special importance. This case is characterized by a constant (in space and time) offshore wind at a normal angle to the straight coastline. Under these idealized conditions, the wave field depends only on the fetch x which is defined as a distance from the shoreline. Highly i...

Wave energy production is one of the most environmentally benign ways to generate electricity. For building of the power stations, that using sea wave motion to generate hydro-pneumatic pressure, which is then transformed into electricity, is necessary to know the characteristics of the sea waves in the interest area. To obtain realistic estimated wind-generated waves for the bottom topography,...

The use of wind power is in a period of rapid growth worldwide and wind energy systems have emerged as a promising technology for utilizing offshore wind resources for the large scale generation of electricity. Drawing upon the maturity of wind turbine and floater technologies developed by the wind energy and oil and gas industries, respectively, large offshore wind energy systems have been dev...
