GEOGRAPHY IN THE NEWS:
"Atmospheric rivers" have been in the news lately as the cause of major precipitation events along the Pacific coast of the U.S. this winter. This article from National Geographic explains atmospheric rivers: "They transport huge volumes of water around the world, carrying it along as vapor and cloud droplets. In an average atmospheric river, about 25 times as much water flows through the air high overhead as through the Mississippi River—and on any given day, about three or four are either developing or flowing through the sky in each hemisphere. 'In a way, they're actually the biggest rivers on earth,' says Marty Ralph, a researcher at the Scripps Institution of Oceanography in La Jolla, California, who been studying the phenomena for years. 'They're just in the air instead of on the ground.' All in all, more than 90 percent of the water that gets moved around Earth's midlatitudes—its midsection, where most of the world's population lives—gets transported via these sinuous sky streams. ... California gets somewhere between 25 to 50 percent of all its annual precipitation from atmospheric rivers." www.nationalgeographic.com/environment/2019/03/atmospheric-river-flood-rain-california-explainer
