A Comparison of Aircraft Icing Forecast Models.

Abstract

This report documents the results of a study comparing forecasted aircraft icing conditions to pilot reports (PIREPs) of aircraft icing. Of the three operational forecast algorithms validated (AF Global Weather Central's RAOB routine, icing routines in the Navy's NODDS, and TESS software), RAOB had the overall best comparison to the PIREPs and 6% percent of the type forecasts and 42 percent of the intensity forecasts agreeing with the reported icing. These percentages increase to 73 percent (type) and 53 (intensity) when considering only PIREPs from jet aircraft. The greatest degree of error was associated with forecasts of clear and mixed icing and icing of moderate intensity.
