Sea Surface Current–Wave–Wind Interactions Measured by Coastal Ground Wave HF Radars

The performance and operational feasibility of the high-frequency Wellen Radar Doppler radar have been demonstrated in a region dominated by strong tidal currents during the SURveillance LITtorale OPerationnelle experiment in Brittany (France). Local weather-oceanic phenomena (current-wave-wind interactions) were measured for the first time by temporal-spatial analyses of the sea surface current measurements, sea surface current spatial gradient, and significant wave heights under conditions of spring tides and current mainly in the wind direction. The results, showing a variation of wave height with the tidal cycle, are presented in this letter.
