In August it was announced that scientists have leveraged the power of a Cray supercomputer at the Pittsburgh Supercomputing Center (PSC) to break new ground in weather prediction.  Researchers from the University of Oklahoma's Center for Analysis and Prediction of Storms (CAPS) and the National Oceanic & Atmospheric Administration (NOAA) employed an innovative combination of high resolution and controlled manipulation of numerical model parameters and starting conditions to develop strategies that will allow forecasters to better anticipate the formation of severe storms and the supercells that give birth to destructive tornados.  The research was part of the NOAA Hazardous Weather Testbed (HWT) Spring Experiment.
