对美国西部84条河流的融雪径流(SMR)时间进行了研究，以了解SMR变化的特征和可能驱动SMR时间变化的气候过程。结果表明，美国西部许多河流的SMR时间已转移到融雪季节的早期。这种转变发生在20世纪80年代中期，伴随着美国西部春季和初夏大气压力和温度的逐步增加。阶梯变化的原因尚未确定。
The timing of snowmelt runoff (SMR) for 84 rivers in the western United States is examined to understand the character of SMR variability and the climate processes that may be driving changes in SMR timing. Results indicate that the timing of SMR for many rivers in the western United States has shifted to earlier in the snowmelt season. This shift occurred as a step change during the mid-1980s in conjunction with a step increase in spring and early-summer atmospheric pressures and temperatures over the western United States. The cause of the step change has not yet been determined.
