本文根据历史水温资料分别建立无维温度θＴ，和无维深度η，进而建立水温垂直剖面的无维自模函数θＴ＝ｆ（η）。在此基础上，利用热传导方程在忽略平流和侧向涡动效应条件下建立描述表层水温（ＴＳ）、底层水温（ＴＨ）和上均匀层厚度（ｈ）的一维模式。利用本模式试报了（时效为５ｄ，１０ｄ，１５ｄ）南黄海２０个站的ＴＳ，ＴＨ，ｈ及温跃层厚度和强度，结果令人满意。
In this paper, the non-dimensional temperature θT and the non-dimensional depth η are respectively established based on the historical water temperature data, and the dimensionless self-modeling function θT = f (η) of the vertical section of the water temperature is established. On this basis, a one-dimensional model describing the surface water temperature (TS), the water temperature at the bottom (TH) and the upper uniform layer thickness (h) is established using the heat conduction equation without considering the effects of advection and lateral whirl. The TS, TH, h and thermocline thickness and strength of 20 stations in South Yellow Sea (age 5d, 10d and 15d) were reported by this model with satisfactory results.
