Changes in extreme regional sea surface height due to an abrupt weakening of the Atlantic meridional overturning circulation
As an extreme scenario of dynamical sea level changes, regional sea surface height (SSH) changes that occur in the North Atlantic due to an abrupt weakening of the Atlantic meridional overturning circulation (AMOC) are simulated. Two versions of the same ocean-only model are used to study the effect...
