The subduct ion sign propagates toward the western tropical pacif ic ; and the decadal sign from the western tropical pacific propagates toward north - east . they meet at about 160 meter in depth in subtropical pacific
从北太平洋窗口区潜沉的海温年代际信号沿西南路径传播到副热带地区，在温跃层160m上下与热带西太平洋向东北传播的海温异常信号会合。
In this paper , features of decadal variability and the possible mechanism of sea - air system in the pacific are investigated by using upper - ocean temperature , heat storage and wind stress data , the main results are as follows : the most pronounce decadal sign exists at about 160 meter in depth in the western pacific . there are significant decadal abrupt changes in temperature from surface to deep in the subsurface at about 1980 . with different depth in the subsurface , there exist 4 types of abrupt change modes , their generation is closely related to the decadal sign which originates from the east of north pacific and propagates along the south - west subduct ion route
研究表明，太平洋次表层海温最强的年代际信号在热带西太平洋约160m深处，此信号在1980年前后从上至下，先后经历了一次显著的年代际突变过程，而且随深度的不同存在着四种不同的空间突变模态，这四种模态的形成与北太平洋海温异常的西南潜沉路径有着密切的联系。
