我们从 8 月 4 日在北华南海(SCS ) 的大陆人架上在一个地点调查了全部水列的当前的速度数据的垂直分发到 2007 年 9 月 6 日，并且发现 barotropic 和 baroclinic 潮的特征主要是日报的。在观察时期期间，我们也估计了在台风 Pabuk 的经过前后混合。我们发现 internal-wave-scale 驱散率，狂暴的驱散率，和在每水层的混合的率在台风经过以后由大约一个数量级增加了。我们以前分析了突然的强壮的电流和计算的混合率的一个案例，在期间，并且在台风事件以后。结果证明在每水层的 internal-wave-scale 驱散率和混合的率在事件期间由大约二个数量级增加了，当狂暴的驱散率由大约一个数量级增加了时。突然的强壮的水流的经过能也由超过一个数量级增加了影响海水的混合的率。然而，台风的经过不同因为仅仅在突然的强壮的水流是特别地强壮的更低的层混合有增加。混合的率的变化可以帮助我们在混合海水上理解台风和突然的强壮的水流的效果。关键词当前的地 - 台风 - 突然的强壮的电流 - 混合率 - 华南海(SCS ) 由中国科学院的知识革新节目支持了(没有。KZCX1-YW-12-03 ) ，为著名年轻科学家，国家高技术研究和开发的中国资金中国(863 程序) 编程序(Nos. 2008AA09Z112， 2008AA09A402 ) ，中国(号码 40676021 ) 的国家自然科学基础，和中国海洋的协会(没有。DYXM-115-02-4-02 ）

英文摘要：

We investigated the vertical distribution of current velocity data of the entire water column at a site on the continental shelf of the northern South China Sea （SCS） from August 4 to September 6, 2007, and found that the characteristics of barotropic and baroclinic tides are mainly diurnal. During the observation period, we also estimated the mixing before and after the passage of Typhoon Pabuk. We found that the internal-wave-scale dissipation rate, the turbulent dissipation rate, and the mixing rate in every water layer increased by about an order of magnitude after the typhoon passage. We analyzed a case of abrupt strong current and calculated the mixing rate before, during, and after the typhoon event. The results show that the internal-wave-scale dissipation rate and the mixing rate in every water layer increased by about two orders of magnitude during the event, while the turbulent dissipation rate increased by about an order of magnitude. Passage of the abrupt strong current could also have increased the mixing rate of affected seawater by more than an order of magnitude. However, the passage of the typhoon differed in that there was an increase in mixing only in the lower layer where the abrupt strong current was particularly strong. The variation of the mixing rate may help us to understand the effects of typhoons and abrupt strong currents on the mixing of seawater.
