The AA. use a variety of spatial analytical methods to assess drought trends in the America Southwest with respect to trends throughout the rest of the United States. Using 1980 as a start of their study period, they show that a highly statistically significant trend toward increased drought has occurred in the American Southwest; the trend is particularly strong over the Colorado River Basin. The primary temporal variance in PDSI values is significantly related to two major teleconnections: the Pacific North American pattern (PNA) and the Atlantic Multidecadal Oscillation (AMO); the relationship with the teleconnections is much stronger in winter than in summer
