摘要
本文根据南黄海风、潮、热通量等实测资料,用stigebrandt的一维模式,对夏季南黄海潮混合锋的位置进行模拟。通过对阳光透射效应和风作用的讨论发现,可以忽略阳光透射对锋的水平位置的影响,而风的作用则是不可忽略的。根据实测锋的剖面结构,文中特别指出,由于浮力平流效应,表层锋水平位置往往与底层锋相距较远,应对二者分别研究。尽管文中的一维模式也不能对受浮力平流影响较大的表层锋准确模拟,但计算结果与实测底层锋符合良好,可见,用此模式来研究底层锋是合适的。
In the paper, the one-dimensional model developed by Stigebrandt is used to simulate the locations of tidal-mixing fronts in Southern Yellow Sea in Summer. Both the effects of sunlight penetrating and wind stirring are studied and it is found that the former are negligible, but the latter are not. Based on the structure of the measured fronts, it is pointed out that the bottom-layer fronts and the surface-layer ones should be studied separately, since their horizontal positions usually, differ remarkly due to buoyancy advection, effect. Although, as other onedimensional models, this model can not correctly simulate the surface-layer fronts which are strongly affected by buoyancy advection, the computed results are in agreement with the observed bottom-layer fronts. It is clear that this model is successful in studying bottom-layer fronts.
