California rushes to prepare for massive ‘Kelvin’ wave and predicted sea level rise
Summary
California is preparing for the arrival of a large underwater warm water wave called a “Kelvin wave,” which could raise sea levels by about one foot along the coast. This wave, caused by a strong El Niño weather pattern, may combine with storms and high tides to cause serious flooding and damage this winter.Key Facts
- The Kelvin wave is a large warm water movement underwater that will reach California soon and move toward Alaska.
- It does not break like regular waves but causes tides to swell from beneath the ocean surface.
- Scientists expect sea levels along California’s coast to rise about one foot due to this wave.
- This rise could double the current 8-12 inch sea level increase already caused by climate change.
- When combined with high tides and storms, the Kelvin wave can worsen flooding and coastal erosion.
- A “super” El Niño weather pattern is making ocean waters warmer and increasing the chance of strong storms.
- California faces its highest tides in November and December, which could make flooding worse during rainy months.
- Experts warn this winter may bring severe coastal flooding and inland flooding, similar to what happened during the 1997-1998 winter.
