Figure 6: Different SPG stratifications in the model sub-ensembles and their comparison with the observational data.
From: Abrupt cooling over the North Atlantic in modern climate models
Present-day vertical profiles of (a) winter density (kg m−3), (c) temperature (oC) and (e) salinity (psu) in the SPG region for observational data (black lines), for ensemble-mean of non-abrupt models (red lines) and for ensemble-mean of the SPG convection collapse models (blue lines). Right panels show the difference between the modelled present-day winter conditions in the SPG and the observation-based data (b) for density, (d) for temperature and (f) salinity. Horizontal dashed lines are drawn at every 1,000 metre. A zoom has been made for the first 1,000 metres.
