Extended Data Fig. 5: Scatter plot of zonal velocity trend against temperature trend and against wind trend.
From: Ocean warming and accelerating Southern Ocean zonal flow
(a) Scatter plot of trend (1979–2014) of upper 100 m zonal velocity relative to 2,000 m depth versus trend of temperature difference between 45˚S and 60˚S, along with the linear relationship for the CMIP6 models: BBC-CSM2-MR, BCC-ESM1, CAMS-CSM1-0, CanESM5, CAS-ESM2-0, CESM2, CESM2-FV2, CESM2-WACCM, CESM2-WACCM-FV2, CMCC-CM2-HR4, CMCC-CM2-SR5, EC-Earth3, EC-Earth3-Veg, FGOALS-g3, FIO-ESM-2-0, GFDL-CM4, GISS-E2-1-G, IPSL-CM6A-LR, MCM-UA-1-0, MIROC6, MPI-ESM1-1-2-HAM. MPI-ESM1-2-LR, MRI-ESM2-0, NESM3, SAM0-UNICON, and TaiESM1. Each red triangle indicates the result of each CMIP6 model. The correlation coefficient is 0.71 across models. The black triangle represents the trend from the IAP product. (b) Scatter plot of velocity trend versus SAM. Each blue square indicates the result from each CMIP6 model. The correlation coefficient is 0.16 across models. The black square represents the SAM trend from ERA5 (observations).
