A good article explaining El Nino and its impactd from one of our own researchers here at UCSB.
"So far, 2026 appears to be a superlative year......The threshold for El Niño is when surface temperatures in the tropical pacific are 0.5º Celsius higher than average for that time of year. Instruments show that the ocean surface is already 4º C higher at the equator. “And the subsurface temperatures are even higher,” Stevenson said. “It's 10º Celsius warmer than normal along the equator.”
Warmer water breeds more intense storms, like Hurricane Polo south of Baja California. This leads to bigger swells and higher surf, important factors in coastal flooding and erosion.
Water also expands as it heats up, adding around 6 inches to the height of the ocean’s surface. This bulge of warm water travels eastward from the equatorial Pacific until reaching the west coasts of North and South America......."
This year’s El Niño already breaking records. Experts at UC Santa Barbara offer their perspective on what they cycle is, what to expect and how to prepare.
