Difference in December–January precipitation anomalies (percent of the 1991-2020 climatology) between the wettest 20% and driest 20% of Southwestern U.S. La Niña outcomes simulated by the GFDL SPEAR climate model. The climate model produces a total of 630 possible climate outcomes covering all La Niñas from 1951-2020. This figure indicates that SPEAR produces very wet early winter conditions in the Southwest for some of the La Niña simulations, with the largest differences between the wet and dry groups exceeding twice the 1991-2020 climatology (more than 200%).
