Influence of atmospheric rivers on precipitation variability in British Columbia’s Gaat Héeni (Silver Salmon River) Watershed

Atmospheric Rivers (ARs) are major drivers of precipitation across western North America, yet their role in inland, leeward watersheds of northwestern British Columbia remains poorly understood. This study develops the first watershed-scale AR climatology for British Columbia's Gaat Héeni (Silver Salmon River) Watershed, a snow-dominated basin that serves as the migration corridor for Sockeye Salmon (Oncorhynchus nerka) returning to Gaat Áayi (Kuthai Lake).
