Kelvin wave

A vast, slow-moving equatorial kelvin wave is heading toward the California coast, prompting warnings that it could strengthen El Niño conditions and raise the risk of extreme weather on the US West Coast. Scientists and commentators are watching the planetary-scale ocean warming pattern closely as concern grows over its potential coastal impacts.

Scientists and news outlets are raising alarms about a slow-moving Kelvin wave — a vast, planetary-scale oceanic phenomenon — that is travelling toward the California coast. Such waves can shift warm water across the Pacific and influence coastal sea levels and weather patterns, prompting concerns about potential impacts on the US West Coast.

Scientists are explaining Kelvin waves, powerful pulses of warm water that travel eastward along the equatorial Pacific beneath the surface. When these waves reach the coast of the Americas, they can push warmer water toward California, potentially affecting ocean temperatures, marine life and weather patterns, including influences tied to El Niño conditions.

Scientists are tracking a massive Kelvin wave — a pulse of unusually warm water moving eastward along the equatorial Pacific — that is now headed toward the California coast. Such waves can raise ocean temperatures, affect marine life, and influence weather patterns, potentially strengthening El Niño conditions and altering rainfall forecasts for the western United States in the months ahead.
