| 摘 要： | 从观测事实和动力机制两方面，对近年发现的新的气候模态——北太平洋涡旋振荡（NPGO）的研究成果进行系统总结。NPGO的空间结构表现为北太平洋上海表高度异常（SSHA）的正负中心呈南北偶极子分布，当NPGO位于正位相时，南北涡流都加强，这种加强是由风应力旋度及风生涌流所驱动的。关于NPGO的机制研究发现，NPGO是中纬太...

| Abstract: | The studies of the new climate mode-North Pacific Gyre Oscillation(NPGO) were reviewed,focusing on the observation phenomenon and dynamic mechanisms.The spatial structure of NPGO mode was characterized by a dipole-like center of the sea surface height anomalies in the North Pacific.The NPGO represented an intensification of both the subpolar and subtropical gyres when in positive phase,and this intensification was driven by open-ocean wind stress curl anomalies and by variations in wind-driven coastal upwel... |
