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 weather watchers are tracking a vast, slow-moving Kelvin wave—a planetary-scale ocean or atmospheric pattern—that is heading toward California. The development is drawing attention because such waves can influence coastal conditions and extreme weather, and concern is mounting over what impact it could bring to the US West Coast.

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.
