受到全球科技化的影響，海軍設備的快速發展，軍事戰備導向高科技、電子化的應用，實施各類型海上作戰任務時，海戰區域的範圍甚大，海戰環境的影響需要精確的評估與預測，故大氣環境與風浪的預測應達到作業化的精確預估，以減低軍事行動可能發生的不確定性。本計畫共分三年度進行，目的為建立台灣環島沿岸之風浪預報模式，以整合海軍氣象中心之大氣預報模式，完成海氣象預報模式的建立。本年度為第一年度，為建立適用於台灣環島之遠域風浪預測模式，評估風浪模式之適用範圍與準確度。第二年度則是建立模式預報流程，依據風浪模式之適用性，進行參數最佳化的調整，並利用資料同化系統以增強模式預報能力。第三年度目標為建立沿岸之風浪預測，並整合三年計畫成果，完成台灣環島海域之風浪預報模式。 Owing to the recent high tech developments, the naval battle region is spreading quickly and widely. Therefore, in order to prevent the warfare mistakes, it needs to estimate accurately about the sea warfare conditions. In the present study, it is proposed to carry out an extensive 3-year project, in order to establish a numerical wave model that conform to the requirements of the naval battle conditions. In the first year, a numerical wave model is planned to develop for the wind wave simulation in the far-sea region. In the second year, using both simulated results and the observational data, it is intended to create a data assimilation procedure that will be used to increase the accuracy of the forcast of the wind wave model. In the last year, an efficient operational procedure for the forecast of the wind wave model will be demonstrated/established. The finer grids in the numerical simulation will particularly be used to enhance the ability of the forcast system. The final objective of this project will be demonstrated by integrating all the different aspects during the last year of the investigation
