Human-driven changes in the westerly winds are bringing hotter and drier springs to the American Southwest, according to new research from the University of Arizona in Tucson. Since the 1970s the winter storm track in the western US has been shifting north, particularly in the late winter. As a result, fewer winter storms bring rain and snow to Southern California, Arizona, Nevada, Utah, western Colorado and western New Mexico.
