| 利用三维有限体积FVCOM近岸海洋模型，通过潮汐和风场共同驱动，建立了渤海精细尺度寒潮风暴潮模型。对渤海潮汐和风暴潮过程进行了数值模拟研究，与实测数据进行比对，对模型进行了验证。利用围填海工程前后的2000年渤海岸线和2010年渤海岸线，对2003年10月的渤海寒潮风暴潮过程进行数值模拟，研究了围填海工程前后，渤海寒潮风暴潮能量场的变化。结果表明，风暴潮期间渤海海域能量场变化明显，曹妃甸港和黄骅港等站位的势能能量密度有相对增加的趋势，动能能量密度有相对减少的趋势，对应的风暴潮水位有增加的趋势，对应的流速有所减弱。在黄骅港站位，势能能量密度大于动能能量密度，总能量密度受势能能量密度的影响较大，总能量密度相对有增加的趋势，在曹妃甸港站位，风暴潮总能量密度受动能能量密度的影响较大，总能量密度相对有减少的趋势。 |

| Based on the three-dimensional finite volume ocean model FVCOM, a fine scale extratropical storm surge model was established in the Bohai Sea. The model was forced by tide and wind field data. The tide and storm surge happened in Bohai Sea was reproduced using FVCOM. The simulated data were verified by the observed data. Using the shoreline of 2000 and 2010, the energy field of extratropical storm surge happened in October 2003 was studied. The results showed the energy field changed obviously at Caofeidian Port and Huanghua Port et al. The potential energy density had a relatively increasing trend and the storm surge elevation increased accordingly. However, the kinetic energy density was relatively weakened and the corresponding velocity was also relatively reduced. At Huanghua Port, the potential energy density was much larger than the kinetic energy density and the total energy density was greatly affected by the potential energy density, so the total energy density tended to increase. At Caofeidian Port, the total energy density of storm surge was greatly affected by the kinetic energy density, as a result the total energy density tended to decrease. |
