This paper compares the Atlantic Meridional Overturning Circulation (AMOC) in global simulations performed with the depth coordinate Parallel Ocean Program (POP) ocean model and with the HYbrid Coordinate Ocean Model (HYCOM) under different surface salinity boundary conditions. When forced by the Coordinated Ocean-ice Reference Experiment (CORE) repeat Normal Year Forcing, HYCOM develops internal inter-annual variability during the model spin-up, while POP does not and HYCOM is more sensitive to the ...
