Fig. 5: Effects of modal horizontal wavenumber change on the energy conversion to M2 internal tides.
From: Enhanced generation of internal tides under global warming
Spectral density of M2 tidal energy conversion (\({\varPsi }_{{{\rm M}}_{2}}\)) as a function of horizontal wavenumber normalized by the mode-1 horizontal wavenumber of M2 internal tides \({K}_{{M}_{2}}^{1}\) during 1995–2004, averaged over the regions with the increased (a) and decreased (b) \({E}_{{{{\rm{M}}}}_{2}}^{1-3}\) under global warming. The color shadings denote the interquartile ranges of \({K}_{{M}_{2}}^{2}/{K}_{{M}_{2}}^{1}\), \({K}_{{M}_{2}}^{3}/{K}_{{M}_{2}}^{1}\) and \({K}_{{M}_{2}}^{4}/{K}_{{M}_{2}}^{1}\).
