EXPERIMENTAL WAVE FORECAST OFF VIETNAM

Collaborators: Prof. Nguyen Thong and Dr. Ho Tuan Duc (Faculty of Civil Engineering, HCMC University of Technology and CARE research center in Vietnam)

DISCLAIMER: Our main goal is to improve our regional forecasting capability through validation using any available information, either from professionals or the general public experience. The achievement of this goal involves the presentation of experimental graphical products, which are provided "as is" without warranty of any kind, including any implied warranties of merchantability or fitness for a particular purpose.

FORECAST DESCRIPTION

WAVEWATCH III is run on a domain spanning the Vietnam East Sea (aka South China Sea). The forecast is for up to 3 days with an output frequency of 6 hours. The forecast uses initial data from the 0.5-degree, 3-hourly product from the Global Forecast System of the National Center for Environmental Prediction (NCEP, NOAA). The simulation starts one day before present using initial data interpolated from GFS.

WAVEWATCH III is developed as a collaboration project led by NOAA/NCEP, with important contributions from SHOM on the wave generation and dissipation parameterizations, and the Technical University of Darmstadt on numerical schemes on triangular meshes (here, structured grids are used). The downscaling of wave fields in the Vietnam region will be computed as a two-way nested solution, i.e. embedded into the regional model. The parent grid resolution of the wave field presented here is 1/4 degree.

Note: GFS is run four times per day (00 UTC, 06 UTC, 12 UTC, and 18 UTC) out to 16 days. For the first week, computation is done at a resolution of about 28-km. The GFS data is then gridded for users on a global 0.5-degree or even 0.25 degree resolution grid.
