Fig. 1: Response of near-bottom buoyancy frequency and depth-averaged buoyancy frequency to global warming.
From: Enhanced generation of internal tides under global warming
a–d Geographical distribution of time-mean (1995–2004) near-bottom buoyancy frequency Nb and depth-averaged buoyancy frequency \(\overline{N}\) in the observation (a, b) and CMIP6 coupled global climate models (CGCMs) ensemble mean (c, d). e, f Projected changes (2091–2100 minus 1995–2004) of Nb and \(\overline{N}\) in the CMIP6 CGCM ensemble mean. Changes insignificant at a 95% confidence level are filled in white. Numbers in white represent the globally averaged changes in percentage as well as their 95% confidence interval. Areas shallower than 500 m are filled in gray and discarded in the analysis.
