VAWS: Future changes in Alaska snow conditions from statistically downscaled climate projections
April 15, 2020 @ 11:00 am to 12:00 pm AKDT
Speaker: Jeremy Littell
Research Ecologist / Lead Scientist

Changes in the cryosphere represent one of the major climate impacts pathways in Alaska. Until recently, projections of future snowpack responses to climate change were geographically coarse scale and poorly tailored to the needs of decision makers and stakeholders. In this presentation, I describe snowpack projections from statistically downscaled precipitation and snow day fraction developed for Alaska. I focus on snowfall water equivalent and a hydrologically relevant indicator of seasonal streamflow. I also present some sub-regional examples developed for specific stakeholder needs in Alaska.
