New scale to measure "atmospheric rivers" on the American west coast – CBS News 8 – San Diego, CA News Station



SAN DIEGO (AP) – Researchers in California introduce a scale to measure "atmospheric rivers", the weather phenomenon that can dump massive amounts of Pacific water on the American west coast, carrying it through the air as far away as Hawaii .

Scripps Institution of Oceanography at the University of California, San Diego announced Tuesday that the 1

to 5 scale will characterize the strength of atmospheric rivers from "weak" to "unusual."

Under system, an atmospheric river in January 2017 would have been category 4 – or "extreme" – because it bleed for 36 hours and produced up to 14 inches of rain in the Sierra Nevada.

Scripps says it resembles scales that measure hurricane, wind or tornado intensity and could help flood response and water management.
