黄海南部温跃层数值模拟——Aken模式的运用

夏季黄海大部分地区的水温分布明显具有上、下两个均匀层。本文利用Aken的一维积分模式,同时考虑了风和潮的湍流混合作用对海洋层化的影响。以4月份观测水温为初值,模拟了1979和1978年4～8月南黄海各月水温的垂直变化。结果表明增温期(5～8月)的数值后报结果与实测符合程度良好,多效测站上、下混合层的预报温度和实测温度之差一般不超过1℃;上、下混合层的厚度及跃层强度分布也同实测一致。

Numerical Modeling of Thermocline in the Southern Yellow Sea-An Application of Aken's One-Dimensional Integral Model

In summer vertical distributions of temperature in most areas of the Yellow Sea are characterized by upper and lower homogeneous-layers. With Aken's one-dimensional integral model of thermocline, the monthly vertical distributions of temperature in the Southern Yellow Sea from Apr. to end of Aug. in 1979 and 1980 were simulated. The calculations show that the hindcast results of temperature profiles by the model are in good agreement with measurements.
