2012年夏末，利用RDI-300 K声学多普勒海流剖面仪（ADCP）在黄海西部冷水团（YSG 1区）38 m水深进行了为期2个月的海底观测。2012年8月，台风波拉文以20 m s−1的最大风速从YSG 1以东经过。测量了水深、底温和剖面流速（包括u、vandw分量），结果表明，台风可在水柱中产生大于70 cm s−1的水平流，特别是在距底20 m以下的区域，这种情况非常罕见。加深的速度剪切层具有约10 cm s− 1 m −1的强烈剪切速度，这表明上部混合层的加深。在上层水柱（20 mb以上），台风向岸涌浪产生了流速大于30 cm s− 1的向西向退潮流，潮流运动方向转向南。在低层水柱中，可能存在一种向东的补偿流和延迟的台风驱动流。台风期间，由于台风和潮流的共同影响，底层温度的变化呈现日变化。Bolaven的通过大大加强了底层的局部沉积物再悬浮。另外，10 mb左右的悬浮颗粒物为低密度颗粒物，可能是台风从南黄海中部输送过来的。总体而言，台风Bolaven的强烈外力并没有完全破坏当地的温跃层，台风期间的大部分再悬浮沉积物被限制在YSCWM。
A two-month seabed-mounted observation (YSG1 area) was carried out in the western Yellow Sea Cold Water Mass (YSCWM) using an RDI-300K acoustic Doppler current profiler (ADCP) placed at a water depth of 38 m in late summer, 2012. On August 2012, Typhoon Bolaven passed east of YSG1 with a maximum wind speed of 20 m s−1. The water depth, bottom temperature, and profile current velocities (includingu,vandwcomponents) were measured, and the results showed that the typhoon could induce horizontal current with speed greater than 70 cm s−1 in the water column, which is especially rare at below 20 meters above bottom (mab). The deepening velocity shear layer had an intense shear velocity of around 10 cm s−1m−1, which indicated the deepening of the upper mixed layer. In the upper water column (above 20 mab), westward de-tide current with velocity greater than 30 cm s−1was generated with the typhoon’s onshore surge, and the direction of current movement shifted to become southward. In the lower water column, a possible pattern of eastward compensation current and delayed typhoon-driven current was demonstrated. During the typhoon, bottom temperature variation was changed into diurnal pattern because of the combined influence of typhoon and tidal current. The passage of Bolaven greatly intensified local sediment resuspension in the bottom layer. In addition, low-density particles constituted the suspended particulate matter (SPM) around 10 mab, which may be transported from the central South Yellow Sea by the typhoon. Overall, the intensive external force of the Typhoon Bolaven did not completely destroy the local thermocline, and most re-suspended sediments during the typhoon were restricted within the YSCWM.
