Title
Length of the Snow Season: All Scenarios [Washington (State)--King County]
Description
Historical, and projected changes in, Length of the Snow Season, which is defined as the number of days between the dates of 10% accumulation and of 90% melt, relative to annual maximum snow water equivalent (SWE). Results are shown only for watersheds with an average historical April 1st SWE of at least 0.4 inch. April 1st is the approximate current timing of peak annual snowpack in the mountains of the Northwest. Geographic units: HUC10. These data include historical conditions (1970-1999) and the projected changes for ten global models. Two time periods are considered: the 2040s (2030-2059) and the 2080s (2070-2099), based on a moderate greenhouse gas scenario (A1B). Data source: Hamlet et al. 2013.
