简介：这篇文章讨论北方大西洋摆动(NAO)和诺思太平洋摆动(NPO)的interannual变化，它与在与气候被联系的中国的interdecadal气候变化的关系在1960鈥檚在北半球跳，用数据分析。两个都，NAO和NPO的振幅在1960鈥檚显然增加，这清楚地被显示出，摆动的主要时期在1960鈥檚前从3-4年改变到8鈥?在1960鈥檚以后的5年。因此，在中国的interdecadal气候变化或气候在1960鈥檚跳仔细与NAO和NPO的异例有关。关键词诺思大西洋摆动(NAO)-诺思太平洋摆动(NPO)-气候跳-Interdecadal气候变化这个工作被国家关键基本科学节目在中国(G1998040903)支持，科学的中国学院和中国(资助No.49823002)的国家自然科学Fundation。作者对为打手稿的王璇女士也感激。

简介：广州春天降雨主要展出内部年变化30年的ofQuasi每年两次、内部的十的变化，并且在时间放大的弱降雨atinterdecadal的时期。Nino3的SST异例(SSTA)是Guangzhouspring降雨的最强壮的先锋。他们从以前的11月有重要积极关联并且稳定地坚持到4月。在以前的冬季的Nino3SSTA在春天通过NorthPacific副热带的高、低的风影响广州春天降雨。当Nino3SSTA在以前的冬季是积极的时，跳副热带的高度是强烈的，向西，华南位于在搬运到华南的副热带的高度，和水汽的边登上气流的区域被反气旋循环加强到菲律宾的东方。广州春天降雨因此是重的。当Nino3SSTA是否定的时，副热带的高度弱、东方，华南从副热带的高度是遥远的并且位于下气流的区域，并且因为低级气旋的循环控制区域到菲律宾的东方，北方风在华南占优势，搬运到华南的水汽是弱的。广州春天降雨因此是弱的，春天干旱被结果。
