本溪县气象站迁站对比观测数据分析

利用本溪县新、旧站点搬迁前2011年逐日平均气温、最低气温、最高气温、相对湿度、平均风速、降水量等资料,运用统计分析对新旧站要素进行对比分析,并建立了新站与旧站气象要素的订正模型。结果表明,站点搬迁造成环境变化大,常规观测要素气温、风速和降水量等差异明显,新站比旧站气温低,湿度、风速偏大;新站与老站温度、湿度、降水等具有较好的相关性,订正模型回代误差小。

Analysis on Comparative Data of Weather Station Relocation in Benxi County

Based on the data of the daily average temperature,minimum temperature,maximum temperature,relative humidity,average wind speed,precipitation of the new and the old site in Benxi County in 2011,using statistical analysis,the old and the new station elements were analyzed,and the revised model was established.The results showed that the site relocation caused environment variation,the observation elements of air temperature,wind speed and precipitation were significant different,the new station was lower than the old station in temperature,humidity,wind speed were larger.New station and the old station temperature,humidity,precipitation,etc.have a good correlation,the revised model back substitution error is small.
