摘要
Laboratory measurements utilizing a laser probe are made for the slopes of wnd waves generated on both positive and negative currents at different values of fetch. The data are then processed electronically to yield an average wave-slope spectrum in frequency space with 128 degrees of freedom. These spectra are used to obtain the growth of the spectral components at various frequency bands for increasing wind and different values of fetch and current. The results indicate that the growth of these components is not monotonic with the frictional wind speed USUP*, but rather exhibits an 'overshot' phenomena aL lower values of USUP*, and in addition, displays a significant effect due to current. The peak location and spectral intensity of the spectra also show strong influence by the current condtions. This results in the rms surface slope value increassng with negative current and decreasing with positive current. The results agree qualitatively with some theoretical predictions. The potential use of the current-induced effects as a means for remote sensing of ocean current is also briefly discussed. (A)
