ABSTRACT. Analyses of observations from four lakes in British Columbia, Canada, compare estimates of the amplitude of thermocline deflections to predictions of wind-driven internal seiche amplitudes made using the Wedderburn number, W. The study sites range from the 750 m diameter Brenda Mines pit-lake to the 107 km long Kootenay Lake. Causal filtering of the wind data with a frequency cut-off based on the fundamental baroclinic time-scale is critical for correct calculation of W. With the filtering incorporated, good comparison between W, its integral equivalent the Lake number L N and the observations can be made. In all but the mine pit-lake, upwelling or near-upwelling conditions (W≈1) were encountered.
