In this study, concerning with the icing phenomenon which is one of the most serious hazards for aviation, a
system was developed providing predictions for the next 24 hours including location, level and time information. This system produces forecasts periodically and represents the results to users. The verification analysis is carried out by comparing the system output with real-time upper level atmosphere observations. After the verification analysis, it is found that the outputs which are produced by this study are practicable for operational meteorology.
