用1993~1999年的TOPEX/Poseidon卫星测高资料, 分析了南海海面高度距平场(SSHA)的平均周年变化; 结合历史水文资料, 反演了多年平均的逐月海面动力地形; 探讨了南海动力地形及其所反映的上层环流季节特征和演变规律. 分析表明, 南海大尺度环流的周年演替可分为4个阶段. 冬季(11~2月)南海环流表现为以北部气旋环流为主的气旋型双圈结构, 相关的特征还包括吕宋海峡的黑潮入侵和加...

Altimetry data from the first 5¼-yr TOPEX/Poseidon mission (October 1992–December 1997) are analyzed focusing on the North Pacific Subtropical Countercurrent (STCC) near the center of the Pacif...
Coupled Pattern Analysis of Sea Surface Temperature and TOPEX/Poseidon Sea Surface Height
Coupled Pattern Analysis Sea Surface Temperature TOPEX/Poseidon Sea Surface Height
