| 摘 要： | 基于盐度观测资料，证实了象山港夏季存在双潮锋的锋面系统，而在冬季该锋面现象消失。本文借助潮锋理论分析了该盐度锋面系统形成的动力机制，并进一步讨论了象山港径流量变化对锋面形成和消退的控制作用。结果表明，丰水期浮力输入是象山港锋面形成的最主要因素。

| Abstract: | Based on salinity observations, a double tidal frontal had been identified in the Xiangshan Bay, Zhejiang, China. The tidal fronts occur in summer season and disappear in winter season. In the paper, the formation of the fronts was discussed by using a tidal front theory which compromises the criteria of h/ 3 and h/ for forming fronts on continental shelves and in estuaries respectively. The genesis and break down of the fronts in the Xiangshan Bay, which are controlled by the fresh water discharge, was also analysed. The study results showed that the input of buoyancy is the most important factor for the formation of the fronts in summer season. |
