摘要:
This paper investigates the causation for the decline of the Atlantic Meridional Overturning Circulation (AMOC) from approximately 17Sv to about 9Sv, when the atmospheric resolution of the Max Planck Institute-Earth System Model is enhanced from similar to 1 degrees to similar to 0.5 degrees. The results show that the slowdown of the AMOC is caused by the cessation of deep convection. In most modeling studies, this is thought to be controlled by buoyancy fluxes in the convective regions, for example, by surface freshwater flux that is introduced locally or via enormous input from glacier or iceberg melts. While we find that freshwater is still the key to the reduction of AMOC seen in the higher-resolution run, the freshening of the North Atlantic does not need to be directly caused by local freshwater fluxes. Instead, it can be caused indirectly through winds via a reduced wind-driven gyre circulation and salinity transport associated to this circulation, as seen in the higher-resolution run.
