摘　　要：在平行轴螺旋桨式风传感器的基础上,制作一个安装于螺旋桨式风传感器风速轴组件上的防冻雨装置,通过这种技术改进,使得改造后的风传感器能在冻雨天气下正常观测,并在中国南极长城站开展了现场试验。通过数据检验分析,改造后的风传感器可有效提升数据可用率,提升了观测连续性,减少了人力劳动。本改进技术对极地地区、我国贵州省等冻雨灾害多发地区的气象观测具有重要意义。Based on the parallel shaft propeller wind sensor,we develop an anti-freezing rain device installed on wind speed shaft assembly of the propeller-type wind sensor.The improved wind sensor works normally in cold rain weather,and is examined at the Chinese Antarctic Great Wall Station.It shows that the improved wind sensor can effectively improve the data availability and the observation continuity,and reduce the cost of human labor.The improved technology is of great importance to meteorological observation in the regions where freezing rain frequently occurs.
