不同风场模式下"灿鸿"台风浪数值模拟及应用
Numerical simulation and application of typhoon CHAN-HOM under different wind field models
摘要
Abstract
For obtaining the optimum synthetic wind field, three different gradient wind field models were combined with ECMWF background wind field respectively to build a new sea surface-driven wind field.In view of unstructured grids, the SWAN model was used to simulate northward typhoon CHAN-HOM, meanwhile, satellite data was used to verify the simulation results.Finally, a conclusion can be drawn that Jelesnianski is the optimal synthetic wind field, followed by Holland, and Fujita is the worst.To provide optimum spectrum boundary for the small scale, Jelesnianski synthetic wind field was selected to carry out the analog computation.In addtion, SWAN nested model was used in order to analyze the simulation results.By contrasting the simulative results with buoy da-ta measured by observation station, it is concluded that the two kinds of results have high degree of coincidence.In comparison with short-term and long-term planning and construction of Nantong coastal waters for regional construc-tion in wave height, it comes to the conclusion that compared with the short-term project, the increase of average effective wave height in the southern waterway is much more notable after carrying out the long-term planning pro-ject, conversely, the average wave height decreases more obviously in eastern waters.关键词
