浅海水温垂直分布模式及其预报方法的研究因国民经济许多部门的需要而成为急待解决的问题之一。然而,由于它的时—空变化十分复杂,加之影响因子众多,垂直热传导机制及海洋中各种尺度的混合过程难以研究,故有成效的方法尚不多见。 七十年代以来,苏联学者和借助于无维变量η、Θ及水温垂直分布自模性的概念,成功地寻求了大洋水温垂直分布的理论无维模式及某些洋区的经验无维模式。这种途径的优点是:(1)回避了混合机制的探讨和涡动粘滞系数的确定;(2)在得到较理想的无维模式以后,仅利用垂直结构的特征值,就能计算出各 The study of the vertical distribution pattern of shallow sea water temperature and its forecasting method has become one of the urgent problems to be solved due to the needs of many sectors of the national economy. However, due to its complicated time-space changes and many influencing factors, the vertical heat conduction mechanism and the mixing process of various scales in the ocean are difficult to study. Therefore, effective methods are still rare. Since the 1970s, Soviet scholars and successfully exploited the theoretical non-dimensional model of ocean water temperature vertical distribution and the empirical dimensionless model in some oceanic regions with the help of the concept of dimensionless η, Θ and vertical distribution of water temperature. The advantages of this approach are: (1) avoiding the discussion of the mixing mechanism and determining the eddy viscosity; (2) using the eigenvalues ​​of the vertical structure only after the ideal dimensionless mode is obtained each
