On low-frequency variations of volume transport of the Pacific western boundary currents

  • 摘要: 基于日本气象厅长时间序列的温、盐度再分析资料,利用动力计算方法分析了北太平洋西边界的北赤道流及其下游黑潮和棉兰老流流量的年际和年代际变化,并探讨了北赤道流变化的可能原因。结果表明,北赤道流和黑潮具有比较一致的年际和年代际变化,均在1976年前后发生了一次气候跃变,之后有长期偏强的趋势,而棉兰老流的年际和年代际变化则有所不同。特别是,北赤道流1976年之后增加的流量似乎大多进入黑潮,而流入棉兰老流的流量则减少。进一步的分析还表明,西传的Rossby波和棉兰老冷涡的变动可能对北赤道流的年际变化有重要影响。
