Numerical experiments are conducted on typhoon Rananim (0414) by use of PSU/NCAR nonhydrostatic mesoscale model MM5.Verified against observations,the track, the speed,intensity change,detailed mesoscale precipitation distributions are well reproduced.

• 利用非静力平衡中尺度模式MM5(V3)对2004年第14号台风Rananim登陆过程进行了数值模拟试验,并对初始场和地形进行了敏感性试验。
