随着筑港向远海、深水、开敞环境发展,缺乏风、浪实测资料严重影响筑港质量和进度。通过对大气科学和海洋学资料收集、模型研究和集成开发,形成以再分析数据和实测数据为基础、中尺度大气模式WRF和第3代海浪模式WW Ⅲ为核心的风浪后报系统。系统采用B/S架构和浏览器作为人机接口、Linux大型并行计算服务器和MPI为模型运行环境,采用网络和指令形式实现WEB服务对模型的控制,采用用户、项目、模型、类型、实例分级实现对大量模型的管理。该系统可对任意海区任意时段的风场、深水波浪场进行后报模拟。实例验证表明,该方法和系统可较好模拟台风场及相应的波浪场。
The lack of actual measruement data of wind and ocean surface wave can seriously affect the quality and schedule of harbor development with the expansion of harbor construction to open water.Through the investigation and research on the data, observations, and models about meteorology and oceanography, based on observations and reanalysis data, integrating the mesoseale meteorological model, WRF, and the 3rd generation ocean wave model, WaveWatehm(wwm), a wind and ocean wave hindeast and simulation system comes into reality. It utilizes B/S architecture and browser as human-computer interface. The models run in a mass parallel computer cluster, named calculation server, with LINUX and MPI as software environment. The model controlling from WWW server is implemented through a web service program which runs in calculation server, receiving instructions from WWW server and then run appropriate model accordingly.Large number of model instances are organized by firstly categorized as WRF and wwⅢ, and then graded into user, projection, model, type and application. This system can hindcast and simulate the wind field in any domain and simulate the ocean surface wave field in any ocean domain. The application of this system shows that this method and system can simulate the typhoon and its wave field correctly.
