Multi-wave analytical benchmark example for our wavelet analysis method. Left : Matsuno-Gill type analytical solution that corresponds to a combination of Rossby waves characterized by n = 1, 1; k = 1, 3. Plotted are the wind fields overlaid on the shallow water height field. Right: scalogram of the zonal wave number against dimensionless time. Our method correctly identifies the input zonal wave numbers, k, and the temporal frequencies, ωr, within the uncertainties, which is due to the Heisenberg-Gabor uncertainty principle.
