Abstract:
The hydrologic system in snowy mountain catchments includes complicated linkages and feedbacks between climate, snow cover, transpiring vegetation, and streamflow. We use 30 water years (1984 – 2014) of precipitation, relative humidity, air temperature, and streamflow data to identify changes that have occurred in the Reynolds Creek Experimental Watershed in Idaho. The process changes that have occurred during this time are presented and analyzed. This unique spatially distributed data set clearly highlights the transition from snow to rain in mountain regions of western North America.
