台湾海峡是一个平均水深大约在七、八十米以内的狭长海峡,外有黑潮水、南海水入侵,内多为入海迳流和闽浙粤沿岸水所影响,且终年为盛行东北一西南季风的海域。水文分布情况,具有明显的季节变化,冬季海水几呈垂直均匀状态;夏季则出现层化现象。对这样多种水系交汇复杂的海区,要进行温度、盐度质量场的分析研究,在缺乏实测流场资料的情况下,显得十分困难。因此,本文从湍流扩散方程出发,采用有限差分法,对台湾海峡局部
The Taiwan Strait is a narrow channel with an average depth of about seven to eighty meters. Kuroshio and South China Sea water are invaded by the Taiwan Strait. Most of the Taiwan Strait is affected by inflows into the sea and coastal waters of Fujian, Zhejiang and Guangdong provinces, and prevails over the northeast-southwest monsoon Sea. Hydrological distribution, with a clear seasonal changes in winter sea water was almost vertical uniform state; stratification in summer there. It is very difficult to analyze and analyze the mass field of temperature and salinity in such a complex sea area where many kinds of water systems converge in the absence of measured flow field data. Therefore, starting from the turbulent diffusion equation, this paper uses finite difference method to analyze the local
