观测站位置环境改变对所获得的气象数据的均一性影响分析—以新疆阿克苏市风资料为例

Analysis of the Impact of Station Location and Environmental Change on Meteorological Data Uniformity—Case Study of Akesu Wind Data in Xinjiang

摘要: 为方便资料用户准确地把握阿克苏国家基准气候站风资料的气候信息，进而揭示真实的风速变化特征与规律，选取阿拉尔、柯坪站当作参考站，运用阿克苏站与参考站从1963~2014a相同时期的风数据依次排列分析其完整性、地区领域的相似性及一致性，研究结果发现，阿克苏站风的数据完整性优良，一致性却非常差。显著性检验结果表明，新址和旧址差异很大，除7月、9月、12月风资料可以连续使用外，其他月份和年资料不能连续使用，在资料服务中需要进行订正，方可连续使用。

Abstract: In order to help the data users understand accurately the climatic information reflected by the wind data of Akesu national reference weather station, and then reveal the real wind speed change characteristic and rules, Alar and Keping stations were taken as the reference stations, and the wind data during 1963~2014a were taken from Akesu Station and the reference stations in order to analyze its completeness, regional similarity and consistency. The result saw excellent wind data integrity but poor consistency at Akesu Station. Significant test results showed great difference between the new and old locations; except the wind data of July, September and December that can be used continuously, the date of other months and the yearly data must be revised with data service, otherwise they cannot be used continuously.
