【摘要】 本文利用PSU/NCAR的中尺度非静力预报模式MM5,采用三重嵌套方案,把浙江省中尺度站的风、压、湿等观测资料通过FDDA技术同化分析进模式,对0414号台风进行模拟,并与不作FDDA的模拟结果进行对比分析,结果表明,MM5对0414号台风登陆前具有较强的预报能力,而把中尺度自动站等资料同化进模式结果明显优于没有进模式的预报结果,尤其是台风登陆后的台风移动路径、降水的预报。
【Abstract】 The typhoon RANANIM(0414) were simulated by using the nonhydrostatic version of mesoscale numerical model MM5 of PSU/NCAR.The FDDA technology was used to observational data of mesoscale autostation of Zhejiang province and other general Sao and Raob in running MM5 model.The constrast experiments were conducted by running without FDDA.The results indicated that the typhoon RANANIM can simulated by MM5 before typhoon landfalling.The observational data using to MM5 by FDDA can notabily improve prediction ability of typhoon,especially prediction of track and heavy rain after landfalling.
