Windows automatically tries to complete more of the update process in the background while you use your PC. This significantly reduces the time your PC will be offline (or unusable) during the update, although it might temporarily use more disk space to complete the update. Windows follows three different feature update paths, depending on the amount of disk space currently available. For more info, see How reserved storage works in Windows. The 8-year contract, with a 2-year optional renewal, provides a total managed service.Note: For devices with reserved storage, an update will first use the reserved storage space before using other disk space. In 2020, NOAA contracted with the company General Dynamics Information Technology (GDIT) on the supercomputer acquisition, upgrade, products and services. Over 20 operational numerical weather prediction models are run on WCOSS. NOAA’s weather forecasting systems and models are developed and managed by the Environmental Modeling Center in College Park, Maryland, which is part of the National Weather Service, in collaboration with NOAA research scientists and the broader modeling community. and new forecasts for surge, tide and waves for Puerto Rico and the U.S. In June, the Probabilistic Storm Surge model upgrade allowed for storm surge forecasting for the contiguous U.S. Earlier last month, the Hurricane Analysis and Forecast System went operational. NOAA has made significant advances to its forecast models since WCOSS was implemented in June 2022. “This increased supercomputing power allows for upgrades to specific modeling systems that will help weather forecasters deliver more accurate weather forecasts, watches and warnings and improved certainty in a forecast,” said Ken Graham, director of NOAA’s National Weather Service. With this upgrade, the twin supercomputers, located in Manassas, Virginia, and Phoenix, Arizona, now operate at a speed of 14.5 petaflops each, and together, the forecast system can process 29 quadrillion calculations per second., NOAA said.Ĭoupled with NOAA’s research and development supercomputers in West Virginia, Tennessee, Mississippi and Colorado, which have a combined capacity of 20 petaflops, the supercomputing capacity supporting NOAA’s new operational prediction and research is now 49 petaflops. Expansion in compute power and storage, which will provide operational capacity to implement research and development advancements made through NOAA’s Earth Prediction Innovation Center.Upgrades to the Global Ensemble Forecast System, which will more accurately capture what is known as radiatively active aerosols to better model emissions such as wildfire smoke, dust and fog.These updates also allow for more advanced high-resolution data-assimilation techniques. A new Rapid Refresh Forecast System, which will allow for larger ensembles with more data included, providing a measure of certainty in a particular forecast that can lead to better decision-making. This upgrade will help smaller-scale features to be seen and simulated, improving model accuracy and overall model performance. The model's horizontal resolution will improve to nine kilometers, compared to 13 in the current version. Global Forecast System will make it higher-resolution. These improvements will permit upgrades to NOAA’s weather forecasting systems and models over the next few years. Faster supercomputing will allow NOAA to run more complex forecast models while increased storage space will enable more data to be fed and assimilated into the system.
