摘　　要：电接风向风速仪自记记录的数字化工作是实施珍贵气象资料拯救工程的一项重要内容。由甘肃省气象局和兰州大学联合承担的中国气象局新技术推广项目———"电接风向风速仪自记记录数字化处理系统开发"实现了对电接风向风速仪自记记录的计算机自动数字化处理。选取逐日电接风向风速仪自记记录,通过对人工挑取的定时和日最大风向、风速值与计算机自动数字化处理值进行比较,分析数字化处理系统的精度。分析结果表明,数字化处理系统对风向风速自记记录识别精度基本符合观测规范要求,同时对人工挑取值的时间订正方法做了一定的改进,系统也极大地提高了数字化的效率。The contact anemometer self- recording records digitization is an important task in the implementation of valuable meteorological information saving work. The contact anemometer self - recording records digitization processing system developed by Gansu Provincial Meteorological Bureau and Lanzhou University is one of the new technology promotion projects of China Meteorological Administration, which realized automatic digital processing of the contact anemometer self - recording records. Based on the day - to - day contact anemmneter self- recording records, the automatic digital processing values were compared with the artificial picks from the timing and the maximum wind direction, wind speed in order to analyze the accuracy of the digital processing system. The results show that the identifying precision of the contact anemometer self - recording records digitization processing system is consistent with the specifications of the observation manual, and the time revise method of the artificial picks is to make a certain improvement. The system can greatly improve the efficiency of the digitization.
