Narrow atmospheric streams of water vapor that deliver heavy rains are more commonly associated with floods and debris flows in northern California than with flash floods in southern California

September 26, 2017 — Around the world, huge streams of water vapor known as atmospheric rivers can generate heavy rain or snow as they flow over land. Just a few atmospheric rivers, each typically more than 2,000 kilometers long and less than 1,000 kilometers Continue reading California Floods Linked to Atmospheric Water Vapor “Rivers”
