Latitudinal velocity spectrum, estimated at the solar equator, for azimuthal orders m = 3 (top), 5 (middle), and 10 (bottom), and for a turbulent Reynolds number Re_turb = 300. The solid red line represents our model, including the contribution both from the inertial modes and from the turbulent noise. The thin blue line shows the solar observations reported by Liang et al. (2019), and the thicker blue line shows the best Lorentzian fit to their data, as reported in their paper.
