对1986—1988年“向阳红09”号5个航次的黑潮调查及日本资料进行了分析,结果指出,这一期间黑潮又发生一次大弯曲现象。本文讨论了这次大弯曲的形成、强盛、衰消过程,认为东海PN断面的流量变异与黑潮大弯曲有一定联系,还对黑潮流量及流轴摆动均作了最大熵谱分析,获得其主要周期。  相似文献   

远州滩—熊野滩外大型冷水团的初步研究     

袁启科  孙湘平  王元培 《海洋科学进展》1989,(2)

作者根据日本出版的海流、温、盐度等资料,对远州滩—熊野滩外大型冷水团的范围,冷水团的中心温度,冷水团的季节变化、多年变化以及大型冷水团的切割分离现象等做了分析与探讨。首次用200米层13℃等温线所包范围视作大型冷水团的面积;指出大型冷水团具有温差大、盐差小、性质比较稳定,以低温为主要特色;认为冷水团的切割现象在黑潮大弯曲史上曾发生过多次,并非罕见现象。  相似文献   

THE SURFACE PATH OF THE KUROSHIO EXTENSION''''S WESTERN SECTOR AND THE EDDIES ON BOTH SIDES     

孙湘平  王元培  袁启科 《中国海洋湖沼学报》1989,(4)

The surface path of the Kuroshio Extension's western sector and the eddies on both sides are systematically analysed based on the GEK-measured surface current and temperature-salinity data from 1955-1985.The main results are shown as follows : 1) According to the position and the features of distribution pattern, the surface path of the Kuroshio Extension's western sector is classified into two kinds (straight and meander ) and seven types (f. ne, Sc, Ui or Vi,Vdi or Udi ,f+v). The straight kind accounts for 1/3 and the meander kind accounts for 2/3. 2) The warm eddies on the northern side originate mostly from the area off Sanriku and Joban of Japan. Their moving paths lie in two patterns: Pattern I, eddy moves northeastward or northward ; Pattern II. eddy rotates about the original area.The cold eddies on the southern side originate mainly from the area off Boso Peninsula. Their moving paths also lie in two patterns: Pattern III,eddy moves from west to east; Pattern IV.eddy moves from north to south.  相似文献
