The seasonal evolution of wind/internal wave resonance in Lake Kinneret

Data from a thermistor chain and wind sensor collected over an annual stratification cycle in Lake Kinneret (Israel) during 2000 were used to investigate the seasonal evolution of wind/internal wave resonance. Internal wave periods determined from an analytical model were compared with observations, and we show that resonance during 2000 occurred during three distinct times of the year-at the onset of stratification (March), during the heating phase (June), and during the cooling phase (November). In till cases, resonance was between the wind and the dominant radial, azimuthal, and vertical mode-one cyclonic (Kelvin) wave previously observed in Lake Kinneret.
