Abstract


A barrier layer (BL) is the layer from the ocean’s isopycnal mixed layer bottom to the top of the thermocline, where density stratification is controlled by salinity. Here, we analyze BL thickness (BLT) in E3SMv1 and two other coupled earth system models. Compared to observation-based climatology, models reproduce the global distribution with semi-permanent BLs in some parts of the tropical oceans and seasonally-occurring BLs in higher latitudes. However, model BLs are generally too shallow in tropical regions and too deep in higher latitudes.
