摘要：

本文将相似理论应用于暖季混合层(温跃层)深度的预报。假设作用过程是非平流和非扩散的。所使用的参数是风、科氏参数、热膨胀系数和混合层内的热储量,在预报模式中应用了Kitaigorodsii的普遍函数概念。最终的预报模式主要包括两个方程,方程中的系数是由1975-1981年暖季东海的实测资料确定的。在东海的两个特点海域中进行的试验证明预报模式具有较好的适应性。

In this paper, similarity theory is applied to the forecasting the depth of them ixed layer(thermocline) during warm season,on the assump-ion that the controlling processes are secular,non-adve ctive and non-divergent.The concept of a universal function P(N) supposed by kitaigoro-dskii is used in the forecasting model and the used parametrs are wind, Coriolis parameter, thermal expansion coefficient and heat storage wi-thin the mixed layer.The resultant forecast model consists mainly of two equations.The constants in the equations are determined by the observed data for the East China Sea during the warm seasons, 1975-1981.The tests apparently indicate a better applicability of this forecast method in two specific sea regions of the East China Sea.
