Witrynaof swell/wind-sea. Our results indicate a high consistency in terms of wave parameters for all deployments. The max-imum significant wave height obtained in the 705 days of observation was 13.41 m. The main spectra found represent unimodal swell dominated cases; however, the dimension-less energy plotted against dimensionless peak … WitrynaSeveral significant improvements in moored buoy wind and wave measurements were made by the National Data Buoy Center (NDBC) in the 1980's. These improvements, …
WitrynaFrom these measurements accurate estimates of the air-sea fluxes can be made. Drifting or moored air-sea interaction buoys will also be needed in WOCE for the verification of the surface data collected by remote sensing.
