"For the first time in nearly 40 years, the National Weather Service’s flagship computer prediction model has received a major makeover, which its leadership says will pave the way for improved forecasts.
The Global Forecast System model, its primary tool for weather forecasting across the nation and around the world, has a new engine, or what scientists call a “dynamic core,” which the Weather Service says “will drive global numerical weather prediction into the future.”
The upgraded model, known as the GFS-FV3 (FV3 stands for Finite-Volume Cubed-Sphere dynamical core), became operational Wednesday."
