drying, while models that simulate a low that extends over the Mediterranean and the Middle East project wetting ( section 2 ). The fact that there is a correspondence between changes in Sahel rainfall and the Sahara low, as defined by geopotential, while no such correspondence can be found with the land–sea thermal contrast, indicates that the details of the anomalous low (its vertical depth and its horizontal extent) are, on one hand, important for the Sahel and, on the other hand, not fully

region is warmer than the subtropics even when the aerosol forcing is generally stronger around equator (the two panels on the right in Fig. 4 ). Nevertheless, the land–sea thermal contrast is clear outside the regions with reduced precipitation such as the large cooling on land over North Africa–Mediterranean and East Asia, seen both in the model and observations. Though not a focus in this paper, the extratropical winter warming discussed in Stenchikov et al. (2004) and Robock (2000) is not

conditions across the midlatitude North Atlantic Ocean, the Mediterranean, including parts of Europe and the Middle East, and central Asia ( Hoerling and Kumar 2003 ). Sparse paleoclimate evidence also indicates that, when North America is dry, it is wet in northern South America; dry in southern South America, southern Europe and the Mediterranean, and equatorial East Africa; and wet in the Sahel, South Africa, and India ( Seager et al. 2007 ). Numerical simulations performed with atmospheric models
