Study reveals link between Tibetan Plateau heat and record rain in California
A new study by University of California, Los Angeles (UCLA) researchers has identified a previously unknown climate connection: abnormally high temperatures on the Tibetan Plateau in early winter can lead to catastrophic rainstorms in California. This link was observed in the winters of 2016-2017 and 2022-2023, when record-breaking rainfall occurred in California and surrounding areas, causing significant damage and fatalities.

A new study by University of California, Los Angeles (UCLA) researchers has identified a previously unknown climate connection: abnormally high temperatures on the Tibetan Plateau in early winter can lead to catastrophic rainstorms in California. This link was observed in the winters of 2016-2017 and 2022-2023, when record-breaking rainfall occurred in California and surrounding areas, causing significant damage and fatalities. These extreme rain events followed periods of unusually high land surface temperatures on the Tibetan Plateau. The study reveals this connection during winters when drier weather was anticipated for the region.
