摘要

摘要: 分析了西北太平洋暖池区2002和2003年夏季ARGO浮标得到的次表层温度和盐度剖面,结果表明大多数台风经过暖池区时,会引起海面盐度下降,这与Kwon和Riser等在大西洋观测到的飓风过后海面盐度上升的结论不同,表明西北太平洋暖池区特有的上层结构以及台风在此海域的降雨与大西洋不同,结果对研究西北太平洋暖池区的混合层混合和热交换过程有重要意义.

Abstract: The temperature and salinity profiles of the ARGO floats in the warm pool of the northwestern Pacific were analyzed.The results show that when typho on passes,the sea surface salinity (SSS) usually decreases in mosto bservations,which is in contrast with that of the observations from the Atlantic Ocean where the SSS usually increases when hurricane passes.This is related to the typical thermal structure in this warm pool region and the differences between the precipitation processes associated with the typhoon in the two oceans.The result is of importance to the study of the heat exchange proceeses and the mixing of the mixed layer in the warm pool of the northwestern Pacific.
