| 1. | One is the open coast model and the other the bay model
第一类是开阔海岸风暴潮模式而另一类是港湾风暴潮模式。 |
| 2. | It achieves the function of the open coast and bay models at the same time
因此这模式同时兼备开阔海岸风暴潮模式和港湾风暴潮模式的功能。 |
| 3. | As tropical cyclones can cover distances of hundreds of kilometres , the area covered by the open coast model has to be large and the grids used in the model correspondingly coarse
由于热带气旋的影响范围可以广达数百公里，开阔海岸风暴潮模式的覆盖范围亦要相应扩大以致模式内网格点间的距离大了，一些细微的海岸线变化如港湾和河口就不能在这网格上显示出来。 |
| 4. | As tropical cyclones can cover distances of hundreds of kilometres , the area covered by the open coast model has to be large and the grids used in the model correspondingly coarse
由于热带气旋的影响范围可以广达数百公里，开阔海岸风暴潮模式的覆盖范围亦要相应扩大以致模式内网格点间的距离大了，一些细微的海岸线变化如港湾和河口就不能在这网格上显示出来。 |
| 5. | The bay model complements the first by using a very fine grid to resolve those geographic features such as bays and inlets at which storm surge observations are absent and where storm surge information is required as design parameters for coastal structures such as embankments
而港湾风暴潮模式的覆盖范围较小，这模式利用一套非常密集的网格点来计算出例如港湾和河口等地理位置的风暴潮资料以补开阔海岸模式的不足。 |
| 6. | As tropical cyclones can cover distances of hundreds of kilometres , the area covered by the open coast model has to be large and the grids used in the model correspondingly coarse . the disadvantage is that small variations in coastlines such as bays and inlets cannot be resolved

而港湾风暴潮模式的覆盖范围较小，这模式利用一套非常密集的网格点来计算出例如港湾和河口等地理位置的风暴潮资料以补开阔海岸模式的不足。当建设沿岸工程如堤坝等需要参考港湾和河口的风暴潮资料而又没有这些纪录时，这套模式便派上用场。 |
