摘　　要：延庆高山滑雪赛区海拔高,局部气候特殊,气象保障团队采用了杯式风传感器与超声测风仪进行联合观测。文章研究了赛事前后的观测数据,分析得出2种传感器数据差异主要由赛道的坡度、湍流及地物影响造成;风传感器结冻现象是由过冷水、气温、相对湿度和风速共同作用产生。超声测风仪的加热功能有效保障了赛事运行期间测风数据的连续性和准确性。应用证实,2种传感器的联合使用,能够满足冬奥会精细化预报服务的要求。The Yanqing alpine skiing area has a high altitude and a special local climate.The meteorological support team uses a cup wind sensor and ultrasonic wind meter for joint observation.After studying the measurement data before and after the race, it is concluded that the difference between the two kind of data is mainly caused by the slope of the track, turbulence and the influence of ground objects.The freezing of the wind sensor is caused by the combined action of super cooled water, air temperature, relative humidity and wind speed.The heating function of the ultrasonic anemometer effectively guarantees the continuity and accuracy of the wind measurement data during the event.The application proves that the combined use of the two sensors can meet the requirements of refined forecasting services for the Winter Olympics.
