| 摘 要： | 利用美国高分辨率中尺度模式WRF(weacherResearch and Forccast)式和、WRF三维同化系统(WRF 3DVAR),以2006年"碧利斯"台风低压引发的暴雨天气过程为例,通过控制试验和同化试验的对比分析,探讨了高空和地面实况资料同化对台风低压"碧利斯"暴雨过程分析和预报的影响.初步的结果显示,同化高空和地面实况资料后对模式的初始场有明显的改进、对暴雨过程的降水落区和强度有不同程度的正反馈,更接近实况的降水.

| Abstract: | Using the high resolution mesoscale model WRF(Weather Research and Forecast) of USA and its 3D assimilation system, taking the rain storm causing by the typhoon low of"Bilis"in 2006 for an example, we compared and analyzed the results of the controlled and assimilation experiment, and then discussed the influence of the assimilation of the real-time data in high layer and surface on our analysis and forecasting.Then we elementarily find that the assimilation of the real-time data in high layer and surface i... |
