The Environmental Working Group (EWG) of the Joint Planning and Development Office (JPDO) is charged with modeling future NAS enhancements. Modeling must consider a number of scenarios under which NAS enhancements will operate. One important scenario is severe en route weather in the CONUS. Because of the complexity of the simulation modeling and limited resources, only a few scenario days will be selected to represent the impact on the NAS of severe weather. A challenge is how to select the days for modeling. On one hand, one could argue that severe weather patterns and movements are quite different each day, making each day unique—this makes selection arbitrary and trivial.
