Numerical simulations of the Proudman resonance

The paper documents numerical modelling exercises designed to reproduce the Proudman resonance on a shelf. Various sinusoidal air pressure disturbances were simulated to travel over the homogeneous waters on a flat or slope bathymetry, qualifying and quantifying the strength of resonance and near-resonance processes in the sea. The results were discussed in light of the worldwide documented destructive meteotsunami events, putting the attention particularly on the effects of the disturbance wavelength, on the weakening of the resonance in near-resonant conditions and on the effect of a slope to the resonance strength.
