| 摘 要： | 对近45年（1951—1995年）前期冬季北半球500 hPa高度距平场和夏季中国降水量进行旋转奇异值分解（RSVD），研究了耦合相关空间分布的区域特性，同时分析了相关型的时间演变。结果表明，旋转奇异值分解有效地揭示了前期冬季北半球500 hPa大尺度流型与夏季中国降水耦合相关型的区域分布特征，并且物理意义明确。利用Galerkin有限元集中质量法，讨论了非饱和土壤水流动的数值计算模型，用以模拟均质土壤，地下水埋藏很深且在不同的初始和边界条件下的水分运动。通过将第一类边界条件齐次化，而对于第二类非线性边界条件采用变分的办法将其直接转化为已知边界通量的计算，从而容易且较好地处理了带通量约束边界条件。对于入渗或蒸发问题，用通常的在分析比较不同地区降水化学特性时，如果列出各种离子的具体数值，既显得繁琐又不容易得出结论。现提出一种简便方法，即先概括出几种最重要的降水化学特性，分别以字母代表，再把这些特性分成几个等级以数字表示，就能很直观方便地比较这些地区的降水化学特性。还利用权威观测资料，以上述方法具体比较了世界主要酸雨地区的降水化学特性。

| Abstract: | The rotated singular value decompostion (RSVD) between the 500 hPa height field anomalies over the Northern Hemisphere the preceding winter and the rainfall in China summer are performed based on both data sets of 45 years in the period of 1951 to 1995. The regional characteristic and the time evolution of the dominant coupled correlation patterns are investigated. The researches show that the regional characteristic of the coupled correlation patterns between the large scale flow patterns during the Northern Hemisphere winter and the rainfall in China summer are identified effectively and have a significant physical sense. |
