Causes and Impacts of the 2016-2019 Southeast Alaska Drought

NIDIS Supported Research
NIDIS-Supported Research
Main Summary

Southeast Alaska, home to the northernmost temperate rain forest in the world, experienced frequent and cumulatively significant below-normal precipitation starting in autumn 2016. Combined with above-normal air and ocean temperatures and changes in economies, the 2016–2019 drought brought wide reaching impacts to individuals, communities, tribes and ecosystems.

Focus areas of this research include:

  • Putting the 2016–2019 drought into historical context
  • Elucidating some of the drivers of the dominant weather patterns during this drought,
  • Documenting impacts across multiple systems and time scales
  • Providing estimates of the future likelihood of such events reoccurring in coming decades through post-processing of available climate model projections.
