Air traffic management requires accurate and consistent weather forecasts to be effective. However, the importance of precision of forecasts is often underestimated. A change in the visibility of only ½ mile can have a pronounced impact on Airport Arrival Rate (AAR), and a change in the ceiling of only 100 feet can impact hundreds of flights. The influence of weather (ceiling, visibility, wind speed/direction, turbulence, thunderstorms) on AAR is strongly non-linear. In another example, air traffic management in both the FAA and industry requires a degree of precision in the location, timing, area coverage, and height of thunderstorms. Precise forecasts of critical weather variables are needed up to 6 hours in advance for effective air traffic management.
