Abstract:

Based on five - layer wind speed, air temperature, humidity and vapor p ressure of the gradient tower of Zhangye National Climate Observatory built in 2007 from Sep tember 2007 to August 2008, the percentage of missing value was calculated, and the climate characteristics of Zhangye in different seasons were also analyzed. The reliability of data from the gradient towerwas checked by comparing with some other observational stations.

Key words: Zhangye National Climate Observatory, wind speed, temperature, humidity, vapor pressure

摘要：

 选取2007年建成的张掖国家气候观象台梯度塔2007年9月至2008年8月5层风速、温度、湿度和水汽压观测资料，统计了这段时期内资料的缺测率，分析了张掖地区不同季节的气候要素变化特征，通过与其他观测台站资料比较，验证了资料的可靠性。
