Local-domain Mesoscale Analysis and Forecast Model Support For The 1996 Centennial Olympic Games


The National Weather Service (NWS) developed the Olympic Weather Support System (OWSS) to provide specialized operational weather support for the 1996 Centennial Olympic Games in Atlanta. Operation implementation of the National Oceanic and Atmospheric Administration Forecast Systems Laboratory's Local Analysis and Prediction System (LAPS) was a key element of the OWSS. LAPS is a complete, three-dimensional data assimilation system that produced subhourly atmospheric analyses on an 8-km grid covering all the Olympic venues. The LAPS analyses also provided initial conditions to the Regional Atmospheric Modeling System (RAMS) mesoscale forecast model. RAMS forecasts were generated at least every 3 h using 8- or 2-km grids. For the first time, a comprehensive operational analysis and forecast system operated iii a local NWS forecast office to support meso-beta-scale forecasts and warnings. Numerous benefits of LAPS-RAMS to the local forecast office were demonstrated. The OWSS, with LAPS-RAMS included, provided a precursory view of the enhanced operational mesoscale forecast capabilities that can be available to the NWS and other forecast offices in the near future.
