Abstract: A 12 hours numerical simulation of typhoon No. 16 1992, from 1200 UTC 31 August to 0000 UTC 1 September 1992, is carried out by using a limited area model developed in Laboratory for Severe Storm Researsch, Peking Universty. The position, intensity, and the heavy precipitation of the typhoon are well simulated in the model. Sensitive experiments shoes that the orographic forcing is crucial on the position and precipitation of the typhoon while the convective cumulus are important in determine the position and intensity of the typhoon.
