Last 12 months, hurricanes hammered the Southern and Eastern US coasts at the price of greater than 160 lives and $70 billion in damages. Thanks to local weather change, it is solely going to worsen. In order to rapidly and precisely predict these more and more extreme climate patterns, the National Oceanic and Atmospheric Administration (NOAA) introduced Tuesday that it has successfully tripled its supercomputing (and subsequently climate modelling) capability with the addition of two high-performance computing (HPC) methods constructed by General Dynamics.
“This is a big day for NOAA and the state of weather forecasting,” Ken Graham, director of NOAA’s National Weather Service, stated in a press assertion. “Researchers 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.”
General Dynamics was awarded the $505 million contract back in 2020 and delivered the 2 computer systems, dubbed Dogwood and Cactus, to their respective places in Manassas, Virginia, and Phoenix, Arizona. They’ll change a pair of older Cray and IBM methods in Reston, Virginia, and Orlando, Florida.
Each HPC operates at 12.1 petaflops or, “a quadrillion calculations per second with 26 petabytes of storage,” Dave Michaud, Director, National Weather Service Office of Central Processing, stated throughout a press name Tuesday morning. That’s “three times the computing capacity and double the storage capacity compared to our previous systems… These systems are amongst the fastest in the world today, currently ranked at number 49 and 50.” Combined with its different supercomputers in West Virginia, Tennessee, Mississippi and Colorado, the NOAA wields a full 42 petaflops of capability.
With this further computational horsepower, the NOAA will be capable to create higher-resolution fashions with extra life like physics — and generate extra of them with the next diploma of mannequin certainty, Brian Gross, Director, NOAA’s Environmental Modeling Center, defined through the name. This ought to lead to extra correct forecasts and longer lead occasions for storm warnings.
“The new supercomputers will also allow significant upgrades to specific modeling systems in the coming years,” Gross stated. “This includes a new hurricane forecast model named the Hurricane Analysis and Forecast System, which is slated to be in operation at the start of the 2023 hurricane season,” and can change the prevailing H4 hurricane climate analysis and forecasting mannequin.
While the NOAA hasn’t but confirmed in absolute phrases how a lot of an enchancment the brand new supercomputers will grant to the company’s climate modelling efforts, Ken Graham, the Director of National Weather Service, is satisfied of their worth.
“To translate what these new supercomputers will mean for for the average American,” he stated through the press name, “we are currently developing models that will be able to provide additional lead time in the outbreak of severe weather events and more accurately track the intensity forecasts for hurricanes, both in the ocean and that are expected to hit landfall, and we want to have longer lead times [before they do].”
