Observations and Modelling of Winds and Waves During the Surface Wave Dynamics Experiment
COASTAL ENGINEERING RESEARCH CENTER VICKSBURG MS
Pagination or Media Count:
This report describes the compilation of observed and modelled wind, wave and current parameters during the third intensive observation period IOP- 3 from February 25 to March 9, 1991, of the Surface Wave Dynamics Experiment. The measurements include wind speed and direction, wave heights and periods, air and sea temperatures, and atmospheric pressures from four directional wave buoys, two meteorological buoys, and several routinely operated buoys from the National Data Buoy Center NDBC. Examples of directional wave spectra obtained from two airborne radars and from a Swath ship are presented along with surface currents from airborne expendable current profilers AXCP and acoustic doppler current profilers ADCP. In addition, a summary of directional wave spectra is presented for this period. The model data include examples of wind fields from six numerical weather prediction models and the corresponding wave height maps as derived from the 3G-WAM ocean wave model. Estimated surface current velocities and directions from the Fleet Numerical Oceanographic Center FNOC model and selected satellite images of sea surface temperature fields are also presented for this time period.
