Extended Data Figure 7: Observed and simulated annual mean tropical rainfall trend patterns for 1979–2012.
From: Tropical forcing of the recent rapid Arctic warming in northeastern Canada and Greenland
Linear trend (mm per day per decade) of annual mean a, observed GPCP31 rainfall, b, simulated rainfall from 34-year simulation of ECHAM run forced by observed SST (1979–2012) in the tropics (30° N to 30° S). In the extratropics and the polar region, the atmosphere is coupled to a slab ocean model with a thermodynamic sea-ice component.
