| 摘 要： | 应用中尺度模式ＭＭ４,使用了一种简单的模式台风处理方法,成功地模拟了８８０５号台风登陆前后的演变及其伴随的特五暴雨过程,即对分析的台风中心物理量场进行修正而形成与实况极为一致的初值,以期能更好地模拟台风过程。从模拟结果可以看出,台风降水强度中心基本上是随台风登陆移动而变化的,每一时期的降水中心基本上与台风移动的路径一致或略偏前方,在登陆时的降水最大,这种降水变化与台风上升运动的烛一致的,上升运动越

| Abstract: | A simple bogus typhoon treatment is used in the mesoscale model MM4 to successfully simulate Typhoon 8805 before and after landfall and associated "unusually heavy rain".For better simulation of the process,the physical quantities around the eye of the storm are modified to produce initialized field that is very close to reality.It is understood that from the modelled results that the center of rainfall intensity is basically variable with the landing and movement of typhoon, being consistent with or a little ahead of the track.The rainfall reaches the maximum at the point of landfall.It is found to change in agreement with the evolution of updraft in typhoon by getting heavier with stronger upward motion. |
