PHYSICAL AND DYNAMICAL SCALES FOR GENERATION OF WIND WAVES

It is attempted herein to summarize results related to mechanism for generation of wind waves and to consider two scales relevant to this intricate process: (1) A physical (length) scale on which coupling takes place between long and short waves and (2) a dynamical (velocity) scale for coupling of wind and waves. Based on these scales and on a separation criterion, it is argued that the airflow separates from dominant waves in the laboratory and from ripples superimposed on dominant waves in the field. This difference may account for the discrepancy between the laboratory-determined growth rate and that measured in the field.
