Analysis on Climate Change Difference of Plain Areas and Mountainous Regions in Hami
Based on the selected long series of hydro-meteorological station data, the difference on Climate change of Plain areas and mountainous regions in Hami was discussed with the linear trend analysis and Mann-Kendal test method, be-cause it is closely related to water resources. . It is found that the variation law and trends of measured annual average monthly series is a close correspondence in Plain areas and mountainous regions, only there are some differences in the amount. Pre-cipitation showed a fluctuations increasing trend, but the trend is not obvious, there was no significant difference in mountains and plains; however, precipitation has obviously increased in Toudaogou stations. Temperature showed a fluctuation rising trend, it was greatly influenced by geographical location, and air temperature raises magnitude of mountainous areas is higher than Plain regions in similar longitude direction. The precipitation of Hamilton weather station and Toudaogou hydrological sta-tion has the most obvious increase in 1960's~1970's, Yiwu weather stations and Weizixia hydrological stations is from 1980's to 1990's. Except for temperatures raised obvious of Yiwu weather station in 1980's to 1990's, other station have the most ob-vious warming in 1970's~1980's.
