Query: Sensitivity of the Atlantic Meridional Overturning Circulation to South
  Atlantic freshwater anomalies   The sensitivity of the Atlantic Meridional Overturning Circulation (AMOC) to
changes in basin integrated net evaporation is highly dependent on the zonal
salinity contrast at the southern border of the Atlantic. Biases in the
freshwater budget strongly affect the stability of the AMOC in numerical
models. The impact of these biases is investigated, by adding local anomaly
patterns in the South Atlantic to the freshwater fluxes at the surface. These
anomalies impact the freshwater and salt transport by the different components
of the ocean circulation, in particular the basin--scale salt--advection
feedback, completely changing the response of the AMOC to arbitrary
perturbations. It is found that an appropriate dipole anomaly pattern at the
southern border of the Atlantic Ocean can collapse the AMOC entirely even
without a further hosing. The results suggest a new view on the stability of
the AMOC, controlled by processes in the South Atlantic.
