Fig. 5: Regression of LC intensity onto surface buoyancy flux and stratification.
From: Inter-model diversity and Its Drivers in Southern Ocean Meridional Overturning Circulation
a LC intensity regressed onto surface buoyancy flux, with coefficients scaled by the standard deviation of surface buoyancy flux so that the units correspond to those of LC intensity. b LC intensity regressed onto Brunt–Väisälä frequency squared (N²) integrated vertically from 1500 to 2000m depth, with coefficients similarly scaled by the standard deviation of N². The dotted areas indicate regions where regression coefficients are statistically significant at the 95% confidence level (Student’s t-test) and corresponding correlation coefficients exceed 0.4. Positive buoyancy flux corresponds to a net gain of buoyancy by the ocean.
