What to know about the Kelvin wave raising the sea level along the West Coast

World 1 source 1 country 🔦 Under-reported 43m ago

A Kelvin wave is currently moving along the West Coast, resulting in a measurable rise in sea levels. Unlike tsunamis, which involve crashing waves, these phenomena manifest as large, traveling bulges of water that elevate the sea surface as they migrate along the coastline.

The movement of these waves is described as similar to water sloshing within a container, such as a bathtub or swimming pool. This event represents a significant oceanographic occurrence that impacts coastal sea levels without the destructive wave-breaking characteristics associated with other marine disturbances.
