Convective WeatherConvective weather is the primary cause of national airspace delay and is also estimated to be the cause of more than half of the serious turbulence injuries. Existing operational forecast products are limited, and provide only 10-20 minute extrapolated positions of storms, with no accounting for storm evolution and only hourly updates of manually created convective SIGMETs.Accurate, automated 1- to 2-hour forecasts of storms would result in the more efficient use of airspace and in reduced delays. Longer term, 2- to 6-hour national forecasts are needed for flight planning and for traffic flow management decisions. The AWRP Convective Weather PDT has developed a 1-hour convective forecast product, using scale separation techniques that not only provide extrapolated positions of storms, but also the effects of growth and decay. This product has been demonstrated as part of the Terminal Convective Weather Demonstration at Dallas/Ft. Worth International Airport and provides the first automated 1-hour storm growth and decay forecast. Contact: webmaster@wx.ll.mit.edu for user ID and password. A National Convective Weather Forecast product took the scale separation technology to airlines for en route utilization. En route advisories of convective weather are provided to airline dispatchers via the ADDS at: http://adds.awc-kc.noaa.gov/.
The majority of the data sources and techniques available for convective weather forecasting are most applicable over the continental US; FAA responsibilities extend over broad ocean areas and Hawaii. Beginning in FY01, AWRP is pursuing capabilities for convective weather products that are specifically intended for oceanic areas.
