摘　　要：通过对2008年1月历史罕见低温雨雪冰冻天气期间气象测风仪器运行情况的分析,以及测风记录缺测原因的剖析,指出应从仪器设计和构造角度出发,通过推广超声波测风仪、改进测风仪器感应器件表面物理特性、改进热力溶冰功能等途径,提高测风仪器抵御冰冻的能力。It is analyzed that the impact of the extreme heavy freezing hazard on the anemometers in the south of China in january 2008. The reasons why the missing wind speed and direction data often appear are also analyzed. In order to provide continuous use even in the most extreme weather conditions, anemometer should be improved through design and constitution. The solutions are ultrasonic wind speed and direction sensors, the hydrophobic coat free from ice and snow, and heated sensors.
