Abstract

Two AGRIF configurations based on NEMO3.6 using LIM2 with high-resolution focus onto the Atlantic Ocean at 1/20°, embedded in ORCA025, have been established. VIKING20X is the successor of VIKING20 with extended high-resolution area over the whole Atlantic from about 68°N to the southern tip of Africa at 34°S. The nest region of INALT20 extends from 10°N, reaching into the southern Ocean at 63°N, also covering the western Indian Ocean.
The two configurations are set up as complementary pair to help to disentangle the influences resulting from an improved representation either of the North Atlantic with its deep water formation contributing to the lower limb of the AMOC or the South Atlantic with its impact from the Agulhas system to the upper limb. Several sensitivity experiments have been conducted focusing on the influence of lateral boundary conditions (free/no-slip) as well as the applied wind stress formulation (relative/absolute winds).
