【摘要】：基于長江口高分辨率FVCOM數(shù)值模型,在率定驗證可靠的基礎(chǔ)上,建立了一個驅(qū)動數(shù)據(jù)下載、模型計算、可視化處理、預報成果發(fā)布的集成自動化操作的長江口咸潮入侵預報系統(tǒng),采用WRF天氣模式進行長江口及臨近海域的風場預測,從而能夠進行未來3 d(72 h)長江口鹽度的三維空間分布以及時間變化預報.并通過該系統(tǒng)后報檢驗了2011年1月份長江口南支堡鎮(zhèn)和崇西的鹽度變化過程,后報檢驗良好.操作便捷、自動化運行等優(yōu)點使得該系統(tǒng)具有一定實用價值,能夠方便及時地對長江口咸潮入侵進行預報.
[Abstract]:Based on the high resolution FVCOM numerical model of the Yangtze Estuary, on the basis of reliable rate verification, a salt tide intrusion prediction system for the Changjiang Estuary is established, which drives data download, model calculation, visualization processing and prediction results. The WRF weather model is used to predict the wind field in the Changjiang Estuary and its adjacent waters. Thus, the three-dimensional spatial distribution and temporal variation of salinity in the Changjiang Estuary can be predicted in the next 3 days (72 h). Through the system, the salinity change process of South Chitzhibao Town and Chongxi in the Changjiang Estuary in January 2011 was tested, and the latter was reported to be good. The advantages of convenient operation and automatic operation make the system have certain practical value and can predict the salt tide intrusion in the Changjiang Estuary conveniently and in time.
