... The comparisons use standardized specifications of model inputs and standardized output formats agreed on by an international committee, and an extensive suite of model outputs is archived and made publicly available for the science and applications communities.4,5 Ekman circulation is the net transport of water due to coupling between wind and surface waters, also known as Ekman transport, resulting from the Ekman spiral (how horizontal wind sets surface waters in motion, in which the speed and direction of water motion change with increasing depth) .6 El Niño–Southern Oscillation (ENSO)

... The water remains open because of processes that prevent sea ice from forming or that quickly move sea ice out of the region.13 Reanalysis refers to the reprocessing of observational data spanning a historical period using a consistent modern analysis system.14 Representative Concentration Pathways (RCPs) are GHG concentration trajectories used for climate modeling and research.15 Rossby Waves are a natural phenomenon in the ocean and atmosphere that owe their properties to Earth's rotation.

... Almost all Southern Ocean or Antarctic sea ice is seasonal sea ice.22 Southern Annular Mode (SAM) is the primary mode of atmospheric variability at high southern latitudes.23 Westerly Winds are winds from the west toward the east in the mid-latitudes (between 30 and 60 degrees)
