dc.description.abstractStrong rain-induced mixing in a thin surface layer is numerically shown to greatly increase surface gravity wave attenuation. This case study uses a single wavelength (2.8 m) together with two mixed layer depths (10 and 20 cm). The rain-induced mixing is simulated by varying kinematic viscosity within the mixed layer from 10"* to 10"^ m- r*' , molecular to strong turbulent mixing, respectively. The results indicate that surface gravity wave attenuation in the presence of a thin rain-induced mixed layer can increase by a factor of up to 60U0 times the attenuation rate due to molecular viscosity alone. This indicates that rain need only mix the top 10-20 cm surface layer to effectively dampen short surface gravity waves.
