Aviation Advisory Climatologies

Additional development of the Convective SIGMET (CSIG) Climatology has occurred since the P5.14 Conference Pre-print was published for the 11th Conference on Aviation, Range, and Aerospace Meteorology. This includes calculating a mean CSIG frequency over pre-defined areas, increasing the data archive resulting in over 10 years of data from January 1995 to the present, giving NCDC the responsibility to generate monthly data for the FAA, calculating average CSIG sizes for each month and year across the CONUS, calculating the frequency of when CSIGs are active near major airports, and comparing CSIG frequencies with weather patterns over monthly intervals.

The CSIG Climatology method has also been applied to other aviation advisories issued by the AWC such as AIRMETs (Icing, Turbulence, IFR, Mountain Obscuration), Non-Convective SIGMETs (Icing, Turbulence), and International SIGMETs (Thunderstorms, Tropical Storms, Turbulence).

Some examples of this information will be presented along with a possible discussion on their potential value in supporting air traffic decisions.
