Abstract In this paper, a severe wind event in Xinjiang on February 27—28, 2007 is simulated and analyzed by the use of the WRF model. The results showed that in addition to impact of weather systems and terrain, the downward momentum transmission of high-level caused by the vertical motion of baroclinic drives is a dynamical factor for the formation of the strong wind; The local adiabatic heating, the increase of sensible heat and latent heat flux, the turbulent above surface layer increasing the instability of atmosphere and producing a strong pressure gradient, and strong cold mass behind the cold front, were the main physical mechanism of the strong wind.
