File:Freshwater transport by the AMOC and Atlantic Ocean freshwater budget.jpg

English: "(A) Freshwater transport by the AMOC at 34°S, FovS. The cyan-colored lines indicate the magnitude of FH. Inset: Zoom in around FovS minimum (model year 1732; fig. S1, C and D), where the FovS mean is determined from cubic splines (here for 50-year averages, see Materials and Methods). (B) Atlantic Ocean freshwater content (W¯ ) difference (with respect to time mean over model years 1 to 50) and with the freshwater content difference of the upper 1000 m (W¯1000↑) and below 1000 m (W¯1000↓). The freshwater budget components of the freshwater convergence (F∇b, freshwater transport at 34°S, 60°N, and the Strait of Gibraltar), surface freshwater fluxes (Fsurf), and changes in the freshwater content ( dWdt). (C) Meridional freshwater transport at the Atlantic boundaries of 34°S and 60°N for the overturning component (FovS and FovN), the azonal (gyre) component (FazS and FazN), and the total freshwater transport (F∇S and F∇N). Positive (negative) values indicate the northward transport of net fresh water (salinity). (D) FovS and AMOC strength over time. The time series are displayed as 25-year averages (to reduce the variability of the time series). The markers indicate the 50-year average over a particular period. The cyan-colored curve indicates the present-day (1994 to 2020) CMIP6 regression and 1 SD (37). The yellow shading in (A) and (D) indicates observed ranges (21, 42, 60, 61) for FovS and AMOC strength."
