根据文献[1]建立的底层温度(T_H)与其水柱垂向平均温度(T)的经验关系T_H=f(T),结合流体动力学方程和(垂向平均)热传导方程,发展了以水气温差和风速为已知量的底层温度二维数值预报模式。该模式,避开了海面热量和动量输入在垂直水柱中分配的复杂物理过程而直接报出底层水温场,具有较好的实用性;此外,从试报的结果看,效果是令人满意的。 According to the empirical relationship T_H = f (T) between the bottom temperature (T_H) and the vertical average temperature of water column (T) established in reference [1], combined with hydrodynamic equation and (vertical average) heat conduction equation, Difference and wind speed are known quantities of two-dimensional numerical prediction model of bottom temperature. This model avoids the complex physical process of the sea surface heat and momentum inputs being distributed in the vertical water column and directly reports the bottom water temperature field, which has good practicability. In addition, the results are satisfactory from the test report .
