How Does El Niño-Southern Oscillation (ENSO) Affect Salmon?

This article was originally published on climate.gov When we discuss the El Niño-Southern Oscillation (“ENSO” for short) at the blog, we often take a rather human or physics-y view of the climate phenomenon. We’ve published loads of articles discussing the mechanics for how ENSO works in the atmosphere and the ocean, and how ENSO impacts humans from droughts and wildfires […]

“NO END IN SIGHT TO THE DRY PATTERN” – Noaa.gov about Tahoe

THIS WOULD LIMIT ANY ATMOSPHERIC RIVERS FROM REACHING THE WEST COAST. ONLY HOPE WOULD BE FOR THE LESS PREDICTABLE PNA TO GO STRONGLY NEGATIVE WITH COLDER STORMS DROPPING FROM THE NORTH, BUT ITS PHASE IS NOT REALLY FORECASTABLE BEYOND DAY 7.” – NOAA.gov’s Reno Office […]
