摘要
本文根据横贯北黄海冷水团的大连—成山角断面的42年观测资料,采用“相似系数”方法分析了北黄海冷水团的分布范围、低温中心位置、厚度、相对体积、温、盐特征等的多年变化特征。根据诸特征的标准离差,将这42年北黄海冷水团划分为强。
According to the 42 years data observed at the Dalian-Cheng Shanjiao section which crosses over the North Huanghai Sea Cold Water Mass,the secular variations of the distribution range,position of cold center,thickenss,relative volume,temperature and salinity characteristics of the North Huanghai Sea Cold Water Mass are analysed by using the method of “similar coefficient'.Bassed on the standar deviation σ(x) of each yaer,the North Huanghai Sea Cold Water Mass in the 42 years are determined as strong,weak or average levels.
