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 mesoscale meteorological model,WRF,and the 3rd generation ocean wave model,WaveWatchⅢ(WWⅢ),a wind and ocean wave hindcast 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.
