The National Oceanic and Atmospheric Administration's National Weather Service just revved up its computer power considerably: The agency's two supercomputers (appropriately named "Tide" and "Gyre") are now operating with 213 teraflops (TF), up from the 90 TF. That means that they can perform 213 trillion calculations per second.
The aim of the amped up computing power is to provide more accurate forecasts that extend further out in time, according to a NOAA release. For example, the agency is going to use the computer to run an improved version of their Hurricane Weather Research and Forecasting (HWRF) model, which shows a 15 percent improvement in forecasting storm tracks and intensity over last year's version, the agency notes.
"Given recent events like the tornado in Moore, Okla., or Superstorm Sandy, federal weather resources and personnel should be considered vital national assets," J. Marshall Shepherd Ph.D., a meteorologist at the University of Georgia and president of the American Meteorological Society, said in the statement.
And NOAA isn't stopping there. By 2015, officials hope to have computing power up to a whopping 1,950 TF.
