摘要： 利用2005—2006年大连自动气象站与人工站观测的温度、气压、降水、相对湿度、0 cm地温和风速风向等资料，对其差值、粗差率、一致率和风向相符率等进行对比分析。结果表明：自动站与人工站气温、本站气压、降水和0 cm地温观测差值较小，其准确度能够满足日常业务使用；而相对湿度、10 min与2 min风速和风向相符率观测差值较大，距离正常业务使用有一定的距离。因观测数据采集方法不同、感应器所处的环境不同、观测仪器原理不同、观测样本不同、观测时间的差异和人为因素的影响是造成对比观测差异的主要原因。

Abstract: Based on the meteorological data including temperature, pressure, precipitation, relative humidity, soil surface temperature and wind speed/direction from automatic weather station (AWS) and manual observation station (MOS) in Dalian from 2005 to 2006, the difference, coarse difference, consistency and corresponding rate of wind direction were compared. The results show that there are small differences on temperature, pressure, precipitation and soil surface temperature between AWS and MOS. Thus, their accuracy can satisfy the needs of routine operation. There are obvious differences on relative humidity, wind speeds of 10 minutes and 2 minutes, and wind direction corresponding rate between AWS and MOS, so it is not suitable for routine operation. The main reasons result from the differences of data collection methods, sensor environment, instrument principles, observation samples, observation time and human factors.
