Of all the major coastal upwelling systems in the World’s ocean, the Benguela, located off south-west Africa, is the one which climate models find hardest to simulate well. Small et al. investigates the sensitivity of a climate model in this region

Global warming drives changes in the salinity and temperature of the ocean interior via modified air-sea fluxes of heat, freshwater and momentum. Lago et al. study tries to elucidate how the knowledge of surface changes impact on the interior of the ocean over a long timescale.

Saba et al. compare simulations and an atmospheric CO2 doubling response from four NOAA Geophysical Fluid Dynamics Laboratory (GFDL) global climate models of varying ocean and atmosphere resolution to understand the enhanced warming of the Northwest Atlantic Ocean under climate change

Atlantic meridional overturning circulation (AMOC) is presumed to play a major role in decadal and longer time scale climate variability and in prediction of the Earth's future climate
