喀什国家基准站迁站前后资料对比分析

利用喀什站旧站址共51a资料(1963-2013年),与同期参考站(选取麦盖提、岳普湖、伽师三站为参考站)资料进行对比分析,结果表明：气温、相对湿度、平均风速资料旧站与参考站的区域一致性较差、均一性较好；另外,用喀什旧站址51a资料与新址2013年资料进行对比分析结果显示：新址与旧址年平均气温、最高、最低气温、降水量数据可以连续使用,月平均气温、最高、最低气温、降水、平均相对湿度资料发生不连续的月份占50%、平均风速全年各月在显著性水平0.05的条件下资料不连续；两站气温差冬季变化最为明显,夏秋季变化相对偏小；平均相对湿度新址较旧址偏高,各季差值在冬季最大；平均风速新址比旧址偏大1.1m/s,冬季偏差稍小；风向相符率仅34.61%,各月差异均很明显。

Data Comparison and Analysis of Kashgar National Reference Climatological Station Before and After Moving

The data collected at the old site of Kashgar Station from 1963 to 2013 was used (the data collected at Maigaiti, Yuepuhu and Jiashi stations during the same period was used for references) to compare with the data collected at the new site of Kashgar Station in 2013, then T test was made with the data collected from the reference stations and the old and new stations. The results show poor difference and regional consistency but good uniformity in air temperature, RH and average wind speed between the old site and the reference stations; the annual average temperature,
