William ‘Bill’ Lapenta, Catalyst of EPIC and the UFS: A Tribute on the First Anniversary of His Passing
On September 30, 2019, the weather community lost a friend, mentor, advocate, scientist, and exemplary leader: Dr. William “Bill” Lapenta, National Centers for Environmental Prediction (NCEP) director (2013-2019) and Weather Program Office director (2019), at the National Oceanic and Atmospheric Administration (NOAA). Bill meant a lot to many of us. Today we take a moment […]
NOAA Implements its First UFS-Based Global-Scale Coupled Forecast System
On September 23, the National Weather Service (NWS) announced a significant upgrade to its operational Global Ensemble Forecast System (GEFS), the first of its kind in nearly five years and first to include atmosphere-wave-aerosols coupling. The GEFSv12 upgrade inaugurates a new era of NOAA’s global forecast capabilities, fueled by innovations introduced by the Unified Forecast […]
