Abstract
A model is presented for the energy loss in the sea surface forward bounce channel due to attenuation from wind‐speed‐dependent bubbles; the model is compared to data from ASIAEX and other archival data sets. At high wind speeds the model predicts an energy loss bound, i.e., no further attenuation with increasing wind speed. Prior to reaching this bound and while there is attenuation, time and angle spreading in the forward bounce path remain largely controlled by the spectral properties of the air‐sea interface, i.e., they remain unchanged by the bubbles. Once bounding of energy loss occurs, initiated by the dominance of bubble scattering over air‐sea interface scattering, time and angle spreading of the arrival change profoundly.
