| 摘 要： | 利用1951-2008年新疆中部15站的实测降水及博斯腾湖部分实测水文资料,用小波分析等统计方法,进一步分析了近20年新疆中部明显增湿的事实。结果表明：（1）新疆中部过去60年交替出现了3段约20年的干、湿期,近20年明显增湿期的平均雨量比气候值增加了约10%～20%。（2）近20年新疆中部的明显增湿主要出现在夏季。（... |

| Abstract: | The obvious moistening fact in Central Xinjiang(CX) in recent 20 years was further analyzed utilizing the observed precipitation data at 15 stations in CX in 1951-2008 and partly hydro-meteorological data and the wavelet technique.The main conclusions are as follows:(1) Both the meteorological and hydrological data show that there exist three dry/wet episodes: i.e.,gait wet one in 1946-1960,evident dry one in 1961-1986,and striking wet one in 1987-2007,in CX in the past 60 years.Each lasted 20 years or so,t... |
