| 摘 要： | 利用欧洲中心月平均再分析资料,通过多种统计诊断方法,分析了高原东部及邻近地区空中水汽资源的气候变化特征,结果表明:1958-2001年以来,区域平均的年大气可降水量总体呈减少趋势,减少率为3 kg·m-2·(10a)-1;区域总水汽收入也呈减少趋势,减少率为6×105kg·(10a)-1;夏季风携带的南来水汽在高原东部及邻近地区扩展强度的减弱是整个区域水汽收入减少的主要原因;在全球气候变暖的背景下,源于中高纬地区水汽输送的影响值得关注.对于本文的研究欧洲中心再分析资料是比较适用的,在定性趋势方面得到的结论是可信的.

| Abstract: | Based on the monthly reanalysis data provided by the European Center for Medium-range Weather Forecasts(ECMWF),features of climate change of water vapor resource overthe eastern region of the Tibetan Plateau and its surroundingsare studied.The monthly reanalysis data provided by the National Centers for Environmental Prediction(NCEP) and radiosonde data provided by China Meteorological Administration are also used to comparativly analyzed.The main results are as follows: From 1958 to 2001,the regional avera... |
