| 摘 要： | 业务化风暴潮计算中多采用模型风场的算法来给出风暴潮强迫场。最大风速半径是模型风场最难确定的参数之一。利用QuikSCAT卫星风场数据拟合台风最大风速半径是确定该参数的有效方法。将拟合得到的最大风速半径代入模型风场计算风暴潮的驱动场,模拟的沿岸风暴增水与实况更为接近。

| Abstract: | Model wind is usually used as forcing field in the operational storm surge simulation.The maximum wind speed radius is one of the parameters which is the hardest to be determined in most wind models.By using QuikSCAT wind data fitting maximum wind speed radii,the storm surge forcing field is assimilated.As a result,the simulated surge is more approximate to the observations. |
