摘要
本文根据黄渤海海区水温资料建立了无维深度η和无维温度θＴ以及相应的水温垂直剖面的相似函数θＴ＝ｆ（η）。在此基础上，设：上均匀层厚度ｈ＝ｈ（ｘ，ｙ，ｔ），表层水温Ｔｓ＝Ｔｓ（ｘ，ｙ，ｔ），上均匀层以下的温度Ｔｚ＝Ｔｚ（ｘ，ｙ，ｚ，ｔ），底层温度ＴＨ＝ＴＨ（ｘ，ｙ，ｔ０，流速分量ｕ＝ｕ（ｘ，ｙ，ｔ）和ｖ＝ｖ（ｘ，ｙ，ｔ）及海面起伏．ζ＝ζ（ｘ，ｙ，ｔ），提出了水温垂直结构的准三维数值预测模式。
By using the observed sea temperature data of the Huanshai and Bobal Seas, thin paper calculated a non-dimensional depth η and its relevant non-dimensional temperature θT and then to construct a similarity function θT= f(η). On this basis, the thickness of the upper homogeneous layer h = h(x,y, t), surface temperature TS= TS (x, y, t), the temperature below the upper homogeneous layer TZ= TZ (x, y, z, t), the bottom temperature TH =TH (x,y,t), current velocity components u = u (x, y, t), v = v (x, y, t) and sea surface topographyξ=ξ(x, y, t) were defined to establiSh a quasi-three dimensional nutherical prediction model of vertical thermal structure. All calculations are made by using 'ADI' and 'HN' methods. The results of a trial prediction with a Period of validity of 4d are satisfactory.
