| 摘要: |
| 利用3种不同模式的初始资料,通过它们生成得到16个不同的初始场,分别对2004年南海及其周边地区9个热带气旋个例进行集合预报试验,最后筛选得到了7个南海热带气旋初值集合成员,由此初步探讨了南海热带气旋初值集合成员的生成方法。结果表明,采用不同模式的初始资料生成得到初值集合成员的方法用于集合预报,对南海热带气旋路径预报有一些明显的改进。 |

| Abstract: |
| Sixteen different initial fields are obtained by using data of different initial fields from 3 numerical forecast models.Seven initial ensemble members for numerical forecast of tropical cyclone track are selected by comparing the effectiveness based on the results of numerical experiments for 9 tropical cyclone cases in the South China Sea or nearby areas in 2004.Here,the method of producing initial ensemble members to predict the track of tropical cyclones in the South China Sea is discussed preliminarily.The results show that some obvious improvements can be obtained for the track forecasting by using ensemble members formed by the data of initial fields of the 3 different numerical models. |
| Key words: ensemble prediction forming initial fields tropical cyclone in the South China Sea numerical experiments |
