摘要:本文计算和分析了南海北部热含量、吕宋海峡和台湾海峡的体积输送和热输送时空变化和季节转换特征,给出了它们的变化的定量结果。研究表明:南海北部热含量并不是一个线形增加或减少的趋势,近50年它有一个盆状的异常变化。吕宋海峡整个深度上输送层化现象比较明显,上层受季风和黑潮共同影响深度在80m左右,受季风影响较大,台湾海峡情况相近,它们的热输送与南海北部热含量有显著的两个月超前相关性,而且有着相近的变化周期。

The heat transport characteristics of the export in northern South China Sea
Abstract:In this paper we calculate and analyse spatial and temporal changes and seasonal conversion features of the heat capacity of the northern South China Sea, volume and heat transport in the Luzon Strait and the Taiwan Strait, and get the results of their quantitative Change. Study shows that: the northern South China Sea heat capacity is not a linear trend of increase or decrease in the last 50 years. It has a basin-shaped anomaly. The phenomenon of transport layer on the entire depth is more obvious in Luzon Strait, the upper depth that is effected by the monsoon and the Kuroshio is about 80m, the greater impact is the monsoon. The situation is similar to the Taiwan Strait, and their heat transport and heat capacity in the northern South China Sea have significant two-months ahead of relevance, but also have similar changes in the cycle.
Keywords: South China Sea Taiwan Strait Luzon Strait flow field heat transport period character
