NOAA turns on GDIT supercomputers to support advanced weather modeling – MeriTalk

The National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service said on June 28 it was beginning the first operational run of weather modeling using new twin supercomputers provided by General Dynamics Information Technology (GDIT) that provide three times the computing power to perform advanced weather. modeling to support.

The dual HPE Cray supercomputers – Dogwood in Virginia and Cactus in Arizona – will produce weather forecast products using the output of the new supercharged model runs. The forecasts are critical to public safety and any economic sector across the country, as well as informing about the impact of space weather on communications, power grids and satellite operations.

NOAA signed a contract with GDIT for the two supercomputers in early 2020 with the goal of upgrading the computing capacity, storage space and connection speed of the US Weather and Climate Operational Supercomputing System (WCOSS).

Improved compute and storage capabilities allow NOAA to deploy higher-resolution models to better capture small-scale features, the agency said. It will also provide more realistic models to better capture cloud formation and precipitation, along with a greater number of individual model simulations to better quantify model certainty.

The result, the NOAA explained, is better forecasting and alerting to support public safety and the national economy.

“More computing power allows NOAA to provide the public with more detailed weather forecasts further in advance,” NOAA administrator Rick Spinrad said in a statement. press release† “Today’s implementation of supercomputers is the culmination of years of hard work by incredible teams across NOAA — everyone should be proud of this achievement.”

“This is a big day for NOAA and the state of weather forecasting,” said Ken Graham, director of NOAA’s National Weather Service. “Researchers are developing new ensemble-based forecasting models at record speed, and now we have the computing power needed to make many of these substantial improvements to improve weather and climate forecasting.”

The new supercomputers will replace NOAA’s previous Cray and IBM supercomputers in Reston, Virginia and Orlando, Florida. Under the initial eight-year contract with NOAA, GDIT designed and acts as the owner and operator of the computers with responsibility for maintaining them and providing all supplies and services, including labor, facilities and computer components.

“Timely and accurate weather forecasts protect every U.S. citizen, every segment of the economy, and play an increasingly important role in emergency preparedness and response to severe weather,” said Kevin Connell, GDIT vice president and general manager for Science and Technology. Technic. “With three times the computing capacity of the current NOAA system, GDIT’s WCOSS supercomputers will enable future upgrades to the National Weather Service’s models, which are essential for accurate and timely forecasts and alerts to protect life and property and US economy,” he said.
