| 摘要: |
| 台风能够对黄海的水文结构及人民群众的生产生活产生重要的影响，严重威胁了人们的生命财产安全。利用ROMS（regional ocean modeling system）模式，分析了台风"灿鸿"在过境黄海期间对黄海温度及环流结构的影响过程。结果表明，台风期间强烈的风致混合能够使温跃层的深度增大，强度减弱，同时，使得近岸的底层温度迅速升高，推动底层的温度锋面向黄海内区移动。台风过境也会对黄海冷水团环流产生重要的影响，台风过境前，混合层中的北向流会迅速加深增强，同时伴随着混合层及温跃层的下移，从而使得黄海冷水团环流的流核下移至跃层以下。当台风过境时，黄海上空的气旋式风场会加剧黄海上层的气旋式环流，导致黄海冷水团环流的流幅及流量迅速增加。当台风登陆后，黄海上层的温度及黄海冷水团环流的结构开始逐渐恢复。 |

| Abstract: |
| Using the regional ocean modeling system (ROMS), the effect of typhoon Chan-hom on temperature and current structure of the Yellow Sea was analyzed. The result shows that, the typhoon induced strong wind-induced mixing, which significantly deepened and weakened the thermocline. Furthermore, bottom temperature in coastal regions was increased rapidly, which pushed the bottom temperature fronts towards the offshore region. Moreover, the typhoon affected remarkably the current structure of the Yellow Sea cold water mass circulation (YSCWMC). When the typhoon approaching, the northward velocity was strengthened and deepened, which deepened the velocity core and shrank the area of the YSCWMC. When Chan-hom passing the Yellow Sea, the cyclonic circulation in the upper layer of the Yellow Sea was enhanced, which intensified the YSCWMC and notably increased its transport. After Chan-hom landed on the Korean Peninsula, the influence of the typhoon gradually attenuated and disappeared. |
