Description:"Thunderstorms account for 24% of weather-related air traffic delays by significantly diminishing the National Airspace System's (NAS) capacity to route aircraft. The NAS is managed at Air Route Traffic Control Centers (ARTCC) by Federal Aviation Administration (FAA) personnel, who receive their weather forecasts and data from co-located Center Weather Service Units (CWSU), operated by the National Weather Service. This study provided real-time mesoscale model output from the Work Station Eta (WSEta) to one of these CWSUs located at Oberlin, Ohio. The model data was assessed to determine whether thunderstorm/convective initiation was forecastable from model fields. In addition anecdotal evidence was sought to determine the data's usefulness to the CWSU forecasters. This study, using a 29 case dataset from August 2004 to June 2005 over the Oberlin CWSU area of responsibility, identified three WSEta meteorological parameters that were credible predictors of thunderstorm initiation: hourly convective precipitation, 700 hPa omega, and 250 hPa divergence"--Abstract.
