Jason J. Levit is Research Associate for the Cooperative Institute for Mesoscale Meteorological Studies, located at the NOAA Storm Prediction Center in Norman, Oklahoma. He has a B.S. and an M.S. in Meteorology from the University of Oklahoma, and his career interests lie mainly in meteorological application development, numerical weather prediction using high performance computers, scientific visualization, and severe storms research.

Talk Abstract
Using OSCER for a Real-Time Ensemble Forecasting Experiment ... and other projects

During the spring of 2003, the NOAA Storm Prediction Center and the National Severe Storms Laboratory evaluated different short-range ensemble forecast (SREF) methodologies, in an effort to understand the use of SREF output for forecasting severe convection. From mid-April through early June, forecaster teams analyzed a 15-member ensemble produced by NCEP, and an experimental 32-member MM5 ensemble, produced through forecaster generated perturbations (via the MM5 adjoint) and computed using a supercomputer at the OU Supercomputing Center for Education and Research (OSCER). The data generated by both ensembles were evaluated using a myriad of statistical post-processing techniques and graphical displays, and were used to generate an experimental Day-2 severe weather outlook for the United States. This talk will focus on the use of OSCER resources for this experiment, and how the custom software designed by OSCER staff helped the experiment run virtually flawlessly. Also, other a couple of other meteorological
