发布时间：2019-07-13 09:54
【摘要】：基于长江口高分辨率FVCOM数值模型,在率定验证可靠的基础上,建立了一个驱动数据下载、模型计算、可视化处理、预报成果发布的集成自动化操作的长江口咸潮入侵预报系统,采用WRF天气模式进行长江口及临近海域的风场预测,从而能够进行未来3 d(72 h)长江口盐度的三维空间分布以及时间变化预报.并通过该系统后报检验了2011年1月份长江口南支堡镇和崇西的盐度变化过程,后报检验良好.操作便捷、自动化运行等优点使得该系统具有一定实用价值,能够方便及时地对长江口咸潮入侵进行预报.
[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.
