subduction

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,太平洋次表層海溫最強的年代際信號在熱帶西太平洋約160m深處,此信號在1980年前后從上至下,先后經歷了一次顯著的年代際突變過程,而且隨深度的不同存在著四種不同的空間突變模態,這四種模態的形成與北太平洋海溫異常的西南潛沉路徑有著密切的聯系。

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 從北太平洋窗口區潛沉的海溫年代際信號沿西南路徑傳播到副熱帶地區,在溫躍層160m上下與熱帶西太平洋向東北傳播的海溫異常信號會合。
