Using the mesoscale numerical model ARPS, a gust front produced by a severe mesoscale convective system happened in Nanjing on 29 June 2006 was examinedand simulated. Numerical simulation result and synoptic situation were analyzed. The analysis of synoptic situation showed that there was obviously temperature inversion layer in the surface layer, and the atmospheric humidity deepened when the process of convective system move closely to the station. Jet stream and vertical wind shear were observed in synoptic situation. Though the thin line echo of gust front was not simulated, but the convergence of cold air descending and outflow from a thunderstorm and environment flow were successfully simulated. The convergence position was just the position of gust front occurring. There were obvious the internal wind stream and temperature construction in the simulation.
