| 摘 要： | 利用新一代中尺度数值模式WRF,对登陆后滞留粤西地区近50 h并带来了暴雨以上强降水的0907号热带风暴"天鹅"进行数值模拟,取得了较好的效果。该模式成功模拟出"天鹅"的移动路径、强度和强降水分布,暴雨的中心强度与实况基本一致。利用模式输出的高分辨率结果分析研究"天鹅"的暴雨降水原因,通过改变地形高度的敏感性试验表明,沿海地区地形的抬升作用对降雨有显著的增幅作用,并且使降水分布更加不均匀。

| Abstract: | After the tropical storm Goni（0907 ） made landfall on Taishan of west Guangdong Procince,it sustained over 50 hours and brought heavy rain. A numerical simulation was performed with the meso - scale model WRF to study the track and precipitation of tropical storm Goni. The comparison of the simulated and the observed showed that the WRF model was able to well simulate the track, intensity and the severe heavy rain of Goni, especially the locations of the heavy rain center areas in the Yang jiang and Jiang men regions. The sensitivity simulation experiments of terrain effect on Goni＇ s heavy rain were also conducted. The experimental results show that orographic lifting contributed greatly to the enhancement of precipitation, and made the distribution of precipitation more uneven. |
