| 摘 要： | 对2004年8月登陆我国的台风"云娜"的热动力结构及其演变进行了数值模拟。试验从大尺度环境场、台风中尺度动力和热力场三维结构、台风云雨特征等多角度,对模拟结果与实际观测进行了对比。结果表明,模式不仅较准确地再现了台风登陆前24h移动和演变的全过程,在移向、移速和登陆时间、地点上与实况十分接近,而且对台风系统中尺度结构、云雨特征的模拟与分析场及卫星观测也有较好的一致性。采用的模拟工具是新开发的双重嵌套AREM模式,该模式是静力模式,但对台风仍有较强的模拟能力。此外,本试验无任何人为台风模型的嵌入是其中的一个特点,从而增加了试验的可信度。

| Abstract: | Simulation of dynamic and thermodynamic structures of Typhoon Rananim was performed using Advanced Regional Eta-coordinate Model(AREM).Two mesh domains with the grid size of 37 km and 12 km were designed to simulate the synoptic scale environment and the storm-scale structure respectively.A Betts-Miller cumulus parameterization scheme and an explicit microphysics scheme were used simultaneously in addition to the non-local PBL parameterization.The model was initialized at 1200 UTC on Aug 11th,2004 with NCEP Analyses.No Bogus data was incorporated.As verified against different observations and analyses,AREM simulated Typhoon Rananim well mainly about the background pattern,3-D thermodynamic and dynamic structures and cloud features.Without Bogus initialization,the model reproduced the evolution of typhoon reasonably from large-scale initial conditions,especially her translation and the landing. |
