摘要(Abstract)：

重点研究西北太平洋长期验潮站海平面变化的季节、年际和年代际变化特征。所选站点多年平均变化速率为1.71mm/a。结果表明,近岸区、大洋沿岸区、大洋区主要周期均为12个月;近岸区、大洋沿岸区、大洋区部分低纬度站点存在6个月周期;所有站点都存在明显的年际和年代际周期信号;中高纬度地区年代际信号强于年际信号,热带地区年际信号强于年代际信号;近岸区、大洋沿岸区、大洋区站点年际和年代际变化具有明显的地域性;热带地区受ENSO影响强于中高纬度地区,热带大洋区受ENSO影响强于大洋沿岸区,热带大洋沿岸区受ENSO影响强于近岸区;受PDO影响较明显的站点位于25°N～40°N的中纬度地区。1993—2010年间,近岸区、大洋沿岸区、大洋区验潮站、大洋区T/P的主要周期均为12个月,但变化速率和季节变化振幅各不同,大洋区验潮站滞后其他区近1个月达到极值。

关键词(KeyWords)： 海平面变化异常值;近岸区;大洋沿岸区;大洋区;SOI指数;PDO指数
