Abstract In order to analyze the air route weather elements and the predictability in Xinjiang,and to construct an air route weather forecast system,this paper uses the voice-based aircraft air reports collected from 2020 to 2021 for statistical analysis.The results show that the air route weather in Xinjiang mainly includes turbulence and icing.The turbulence mainly occurs in the upper layer and is mainly caused by jet stream.The icing mainly occurs in the middle layer and is mainly caused by the trough aloft.Therefore,the numerical prediction can be used to diagnose and analyze the turbulence and icing.The WAFS (World Area Forecast System) products provided by the World Regional Forecast Center include high-resolution diagnostics of turbulence and icing.Using this data to construct an air route forecast system in Xinjiang can provide point-to-surface blending products for users and provide objective and reliable route weather references for flights.
