Credit: NOAA Earlier this week, my good friends at NOAA (well, hopefully we’ll be best buds someday) issued a La Niña watch for the Tropical Pacific. Some of the models were showing a transition to a La Niña for next winter in the months before, but there was enough spread and uncertainty in the models […]
El Niño–Southern Oscillation (ENSO) – For Dummies

The La Nina has strengthened slightly, and although it won’t become as strong as last year’s, all indications […]
What is El Nino Southern Oscillation? (ENSO)
El Nino and La Nina are both part of the El Nino Southern Oscilliation (ENSO) pattern in the eastern tropical Pacific ocean. This oscillation, or switching, refers to the temperature of the water in that region. In a La Nina phase, the water temperatures are cooler than normal, and in an El Nino phase, the […]
