摘　　要：随着气象现代化的快速发展,越来越多的台站已经投入使用自动气象站,而自动气象站风速传感器作为气象要素风速的测量仪器,所以对其准确计量很有必要。通过省气象局长期业务运行反映,将风速传感器与标准皮托管安装于同一试验段进行测试时,由于阻塞以及风杯扰动对标准风速的测量产生很大的影响。为此,本次试验将风速传感器与标准皮托管安装于不同试验段,进行测试数据统计分析。结果表明:自动气象站风速传感器与标准皮托管安装于不同试验段进行测试时,减少了风速传感器自身扰动对标准风速测量的影响,使得测试结果更加的准确、可靠。With the rapid development of meteorological modernization,more and more stations have already put automatic weather stations into use,and wind speed sensors of automatic weather station are used as measuring instruments for wind speed as one of meteorological elements,it is very necessary to accurately measure them.Through the long-term business operation of the Provincial Meteorological Bureau,when the wind speed sensor and the standard pitot tube are installed in the same test section for testing,the blockage and the wind cup disturbance have a great influence on the measurement of the standard wind speed. Thus,we installed wind speed sensor and standard pitot tube in different test sections for statistical analysis of test data. The results show that when the automatic weather station wind speed sensor and the standard pitot tube are installed in different test sections for testing,the influence of disturbance of the wind speed sensor put on the standard wind speed measurement is reduced,and the test result is more accurate and reliable.
