Simulation and Analysis of the Thermal-dynamics Characteristics of "2.28" Severe Wind Event in Xinjiang with WRF Model
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.
