英文摘要: California has experienced severe drought in 2012-2014 (which appears to be continuing into 2015), with especially low winter precipitation and mountain snowpack in winter 2013-2014. However, the extent to which climate change is implicated in the drought, if at all, is not clear. By applying modeling and statistical approaches, we construct a historical record of California snowpack, runoff, and other hydrological variables of almost 100 years in length and use the reconstructed records to analyze climate trends in the Sierra Nevada and their impact on extreme drought events in the historic record. We confirm a general warming trend and associated decreasing trends in spring snowpack and runoff. We find that the warming may have slightly exacerbated some extreme events (including the 2013-2014 drought and the 1976-1977 drought of record), but the effect is modest; instead, these drought events are mainly the result of variability in precipitation. ©2015.
