| 摘 要： | 目的]研究我国西北干旱区春季降水与全球海温的相关特征。方法]利用1979～2008年GPCP全球逐月降水资料和NOAAERSST海温资料,采用相关分析和合成分析等方法,分析了西北干旱区30年来降水特征及其与全球海温的相关分布特征。结果]1979～2008年西北干旱区春季降水量均呈波动增加;15°S～22°N、45°～105°E范围的印度洋海温对西北干旱区春季的降水具有持续性影响,可以作为一个预报西北干旱区春季降水的稳定因子。印度洋、孟加拉湾、阿拉伯海地区的海温偏高时,春季西北干旱区的降水有可能偏多;同时前期夏、秋、冬季赤道东太平洋附近的海温若偏高,对于次年西北干旱区春季降水很有利;阿拉伯海、中印度洋以及西太平洋地区的海温场是影响西北干旱区春季降水的关键因素。结论]该研究为干旱区降水的预测预报提供理论依据。
