基于第三代海浪模式,采用四重嵌套网格,建立了WaveWatchⅢ和SWAN嵌套(方案一)和SWAN自嵌套(方案二)两套台湾海峡及其近岸区域海浪预报系统。通过对一次台风过程3天和7天的海浪预报实验,对两套预报系统作了检验。结果表明,方案一的3天和7天的预报误差分别为14.78%和19.53%,方案二的分别为10.38%和15.85%。两套系统的预报精度均能达到海浪精细化业务化预报要求。 |
Based on the third generation wave model with the fourfold nested grids, the two fine-scale precision wave forecasting systems in the Taiwan Strait are established. One is inter-nest between the WaveWatch Ⅲ and SWAN (case 1) and another one is self-nest of SWAN (case 2). The wave predicting ability is examined by a typhoon process in 3 days and 7 days forecasting. The results show that the relative error of forecasting for 3 days and 7 days in case 1 are 14.78% and 19.53%, while in case 2 they are 10.38% and 15.85%, respectively. Therefore, both the two systems could satisfy the operational demand. |
