Fig. 4

a Contour plot shows the dependence of horizontal wavelength \(\lambda _h\) with time-period (T) and vertical wavelengths \((\lambda _z)\) of the simulated monochromatic GWs. b Orange dotted line shows the input frequency spectra with a power-law slope of − 2. The black and blue line plots illustrate the spectra estimated by the WCFI with 50 km horizontal resolution and MWE method, respectively, using the GW model simulation. c Black line plot shows the WCFI spectra estimated with 500 km horizontal resolution. The blue and orange plots are identical to plot (b), which are added for comparison
