Hurricanes and tornadoes have ratings, now atmospheric rivers do too. The atmospheric river intensity scale or AR-X scale could help predict the severity of dangerous storm systems.

The atmospheric river intensity scale

A recently developed scale for atmospheric river intensity can be used to identify the hotspots of the most intense atmospheric rivers worldwide. The study shows that this scale, which ranks atmospheric rivers from AR-1 to AR-5 based on their duration and moisture transport, is no longer just a meteorological term, but it also helps communities…
