| 摘 要： | 利用2003年1月至2004年12月兖州自动气象站观测资料和人工观测资料,对各气象要素进行了对比分析并探讨了两者差异形成的原因。结果表明:两种观测方式的观测数据虽然有一定差异,但在允许的精度范围内,其中平均地面最低温度、平均地面最高温度、地面极端最低温度和地面极端最高温度总体差值较大。除仪器的性能和工作原理造成的差异外,观测环境的变化、人为操作和特殊的天气现象也是造成差异的重要原因。

| Abstract: | The contrastive analysis is made based on the data from automatic weather stations(AWS) and conventional stations from January 2003 to December 2004 at Yanzhou Weather Station.All the essential meteorological elements are compared and analyzed,and the reasons for discrepancy are discussed.The result shows that though there is certain discrepancy in data from two observation approaches, the errors are within the permitted limits.The discrepancies in average ground minimum temperature,average ground maximum temperature,ground extreme minimum temperature,and ground extreme maximum temperature are relatively greater.The causes of the discrepancies(except for those resulted from the design and capability of the instruments),the changes of observation environment,and factors relevant to artificial operating and special weather phenomenon are also discussed.The findings are of significance to the application studies of automatic weather stations and the precision of AWS observation data. |
