热带西太平洋上层热结构和海流异常及其对副高的影响
-
摘要: 本文以中美双边TOGA考察期间所获得的资料为主,说明了1986/1987年埃尔尼诺期间,热带西太平洋上层热结构和海洋环流的异常变化.讨论了这些异常变化对西北太平洋副热带高压的影响.在埃尔尼诺期间,(1)热带西太平洋东部(以165°E断面的次表层温度资料为代表),高于29℃的表层暧水沿经向扩展,使大面积的海表面出现温度正距平;(2)在热带西太平洋西部(以137°E断面的次表层温度资料为代表),表层暖水(T>28℃)的横截面积变小;表层温度出现负距平;(3)165°E断面的上层东向流增强;(4)从黑潮源地,即18°20'N以南、130°E以西至菲律宾沿岸的热带洋域向北的暖水流量变小.在这些异常变化发生时,西北太平洋低空(1 000hPa)的大气辐散加强,这有利于西北太平洋副高的加强.
