A Kelvin wave has reached California and is creeping up the West Coast, raising both sea levels and concerns from government officials. This kind of massive internal wave begins in the western Pacific Ocean and then travels eastward to the Americas along the equator, and then up and down the coastline. While it might raise sea levels up to 12 inches, it stays below the surface instead of crashing on the shore.
Host Flora Lichtman speaks to oceanographer Andrew Leising to get the lowdown on what exactly a Kelvin wave is, and how wary West Coasters should be.
This is a lesser known but vitally important part of Calvinball.
