NOAA's new supercomputers, first announced in February 2020 with a contract award to General Dynamics Information Technology (GDIT), provide a significant upgrade to computing capacity, storage space and interconnect speed of the nation\u2019s Weather and Climate Operational Supercomputing System.

\n\u201cAccurate weather and climate predictions are critical to informing public safety, supporting local economies, and addressing the threat of climate change,\u201d said U.S. Secretary of Commerce Gina M. Raimondo. \u201cThrough strategic and sustained investments, the U.S. is reclaiming a global top spot in high-performance computing to provide more accurate and timely climate forecasts to the public.\u201d
\n
\n\u201cMore computing power will enable NOAA to provide the public with more detailed weather forecasts further in advance,\u201d said NOAA Administrator, Rick Spinrad, Ph.D. \u201cToday\u2019s supercomputer implementation is the culmination of years of hard work by incredible teams across NOAA \u2014 everyone should be proud of this accomplishment.\u201d
\n
\n\u201cThis is a big day for NOAA and the state of weather forecasting,\u201d said Ken Graham, director of NOAA\u2019s National Weather Service. \u201cResearchers are developing new ensemble-based forecast models at record speed, and now we have the computing power needed to implement many of these substantial advancements to improve weather and climate prediction.\u201d
\n
\nEnhanced computing and storage capacity will allow NOAA to deploy higher-resolution models to better capture small-scale features like severe thunderstorms, more realistic model physics to better capture the formation of clouds and precipitation, and a larger number of individual model simulations to better quantify model certainty. The end result is even better forecasts and warnings to support public safety and the national economy.
\n
\nThe new supercomputers will enable an upgrade to the U.S. Global Forecast System, the "GFS," this fall and the launch of a new hurricane forecast model called the Hurricane Analysis and Forecast System, the "HAFS," slated to be in operation for the 2023 hurricane season pending tests and evaluation.
\n
\nIn addition, the new supercomputers will enable NOAA\u2019s Environmental Modeling Center \u2014 a division of the National Weather Service\u2019s National Centers for Environmental Prediction \u2014 to implement other new applications created by model developers across the U.S. under the Unified Forecast Systemoffsite link over the next five years.

This week on the Carolina Weather Group, we chat with David Michaud, the director of central processing for the National Weather Service, and Brian Gross, the director of environmental modeling for NWS.
