Kelvin Wave

Scientists are tracking a slow-moving, planetary-scale Kelvin wave in the Pacific that is heading toward the California coast. The ocean phenomenon could raise sea levels along the coast by up to a foot, with El Niño conditions keeping warm water trapped near the shoreline. Observers are watching for increased coastal flooding and erosion risks as the wave arrives.

A Kelvin wave is a pulse of unusually warm water that travels eastward along the equatorial Pacific, pushing warmer water toward the Americas. Scientists are tracking current Kelvin wave activity because a strong pulse reaching the West Coast could raise ocean temperatures near California and influence weather patterns, potentially adding to signs of El Niño conditions developing.

Climate researchers are explaining how a Kelvin Wave affects ocean waters. A Kelvin Wave is a large-scale movement of warm water along the equatorial Pacific that can raise sea surface temperatures and influence weather patterns, including developments tied to El Nino. Scientists say understanding these waves helps forecast shifts in ocean conditions and global climate impacts in the months ahead.
