| 摘要: |
| 江苏海域是绿潮灾害的多发海域, 本文利用MIKE3模型建立了江苏辐射沙洲重点海域三维水动力模型, 并采用实测资料对模型进行验证和率定; 在水动力模型的基础上建立绿潮漂移扩散模型,对江苏海域绿潮漂移路径进行了模拟并与卫星遥感监测的结果进行对比。对比结果表明, 模型24 h和48 h模拟结果与卫星遥感图像分析结果较吻合, 模型能为江苏海域绿潮的预警预报提供一定参考。 |

| Abstract: |
| Green tide occurs frequently in the sea areas of Jiangsu Province. In this paper, a 3-D hydrodynamic model of the sea area around the radial sand ridge was established by the MIKE3 model, and used the observed data to carry on the model validation and parameter calibration. Based on the hydrodynamic model, the green tide drift and diffusion model is established. The green tide drift path is simulated by using the model. Compared with the satellite remote sensing monitoring, the simulation results of 24 hours and 48 hours are very consistent. The model can provide some reference for the early warning and forecasting of the green tide in Jiangsu sea area. |
