Abstract :
Wave-tank measurements show that some wind waves travel at a speed that corresponds more closely to the spectral peak frequency than to the linear dispersion relation. However, Bragg echoes sampled and averaged in space and time by HF radars tend to obey the linear dispersion relation. Resolution of the dilemma will require new measurements with incisive attention to their meaning.
