应用Argo剖面浮标观测的温、盐度资料,分析了西北太平洋海域冬、夏季的温、盐度分布、水团结构及其分布。首先采用T-S点聚图法分析了该海域水团分布的基本情况,由点聚分析结果可知,该海域至少存在6种以上水团;再用模糊聚类软化法对水团作进一步划分,分别计算了该海域6至11类水团的F和△F值,结果表明,冬、夏季的△F值都以划分为8类时为最大,这与大洋水团的稳定性是一致的,因此,该海域冬、夏季水团以划分为8类最佳,它们分别是北太平洋热带表层水、北太平洋次表层水、北太平洋中层水、北太平洋副热带模态水、北太平洋深层水和赤道表层水,以及南太平洋次表层水和南太平洋中层水。
The temperature and salinity data observed by Argo profile buoys were used to analyze the distributions of temperature and salinity, water masses and their distributions in winter and summer in the northwestern Pacific Ocean. Firstly, the basic situation of the water mass distribution in the sea area was analyzed by TS point polygraph method. According to the results of point poly analysis, there were at least 6 kinds of water mass in the sea area. Then the water mass was further divided by fuzzy clustering softening method The F and △ F values of water masses from 6 to 11 were calculated. The results showed that △ F values of winter and summer were the largest when they were divided into 8 groups, which was consistent with the stability of oceanic water masses The water masses in winter and summer in this area are divided into 8 groups, which are the best in the North Pacific tropical surface water, the North Pacific sub-surface water, the North Pacific middle water, the North Pacific subtropical water, the deep water in the North Pacific and the equatorial surface Water, sub-surface waters in the South Pacific and mid-level waters in the South Pacific.
