Operational weather support system for Aviation Meteorology Center (AMC) at CAAC is developed based on enterprise integrated aviation weather system (eIAWS®) and aims at improving the overall efficiency of air traffic system. The system includes a short-term severe weather nowcasting module, imNOWCASTERTM, a Regional Rapid Refresh data assimilation and numerical model predication module (R3R), Numerical module output Blending and Interpretation (NBI) and Numerical module output and forecast product verification (NFV). The weather-related products from the three modules will be used to support current AMC operation. Nowcasting module provide a 2-hour severe weather forecast every 10 minutes using weather radar reflectivity mosaic and satellite observation. The R3R module provides a 12-hour forecast hourly. In this module, radar, satellite, METAR, AMDAR, sounding and other available meteorological observation are assimilated every hour to initialize NWP with the latest atmospheric condition. The NBI module blends the output from different NWP and produces aviation weather products. The NFV module evaluates the NWP forecast product and forecaster’s forecast. The NFV generates a platform to compare the forecast product from different NWP and forecaster. It is expected to improve the forecasting skills through analyzing the result of the objective verification. The above modules provide full meteorological support at AMC. The details of the system will be reported in the conference.
