本文结合广汉地方气候特点。对WAFS数值预报资料进行整理、诊断，转换GRIB数据，并根据WAFS资料计算了露点温度的预报值，由此得出一些预报产品，如降水预报、形势场预报、K指数、假相当位温、结冰指数等。在实际工作中，使用WAFS预报产品多次准确预报了广汉机场的大风、降水等重要天气过程。同时，也发现WAFS资料在强度预报和长期预报中的不足。

This article combines the local climate characteristics Of Guanghan area, carries on the reorganization and the diagnosis to the WAFS numerical forecasting materials, transforms the GRIB data, and has calculated the dew-point temperature forecast value according to the WAFS materials. This research obtains some forecast products, like the precipitation predict that shapes potential field predict and the K index, the vacation potential equivalent temperature, ice up index and so on. In practical work, we use the WAFS forecast products to forecast the gale and precipitation accurately many times at Guanghan Airport and find the important synoptic process. At the same time, we have discovered the deficiencies of the WAFS material in intensity forecast and long-term forecast.
