The next-generation weather forecast model that Lin and his team at the Geophysical Fluid Dynamics Laboratory in Princeton have devised, called FV3, is about to become a linchpin for U.S. meteorologists.
Louis Uccellini, director of the NWS, describes FV3 as “a major breakthrough” and tells TIME that progress is now ahead of schedule, with the revamped model set to exit testing and become operational in early 2019. The goal: put the U.S. global forecast model back on top in a world being reshaped by climate change. In this summer of extreme events, from brutal heat waves to deadly forest fires, everyone wants to know what the weather will do next.
