摘　　要：现有的数据质量控制标准中未对风向数据时间一致性检查设定最大允许变化范围,文章通过对新型站风向分钟数据及同一观测环境下两套风向传感器数据对比分析,确定了风向变化较为合理的最大允许变化阈值,并对差值较大的原因进行了分析。研究结果为改进观测数据质量控制方法提供了参考。The current data quality control standard has not set the maximum allowable change range for the time coherence check of wind direction data.By comparing and analyzing the minute data of the wind direction of the new station and the data of two sets of wind direction sensors under the same observation environment, this paper determines the reasonable maximum allowable change threshold of wind direction change, and analyzes the reasons for the large difference.The research results provide a reference for improving the quality control method of observation data.
