Six aviation weather hazard areas are currently being addressed at the National Center for Atmospheric Research (NCAR) Research Applications Laboratory (RAL) through emerging weather products: convection and convective hazards; in-flight icing; turbulence (terrain-induced, convective-induced, jet stream, and shear); remote and oceanic weather hazard diagnosis and forecasts; ceiling and visibility, and winter weather hazards on the ground. These products are being transitioned to operations for use by pilots, dispatchers, flight service specialists, and air traffic controllers/managers. Underlying research, verification, dissemination methods, and user interface/display development have been sponsored primarily by the FAA Aviation Weather Research (AWR) Program, with joint sponsorship from the NASA Aviation Safety Program (AvSP). This paper describes integrated methods of diagnosing and forecasting aviation weather hazards using "fuzzy logic" or expert system framework techniques, and the current status of operational transition of these revolutionary new products. It will also describe methods of getting the most current weather information to the end user, including data link and real-time display in the cockpit. Since these new products are four-dimensional, unique display concepts for the end user will also be covered. Finally, issues relating to how these new products can provide decision support to air traffic managers are identified.
