نبذة مختصرة : In order to analyzed the model simulation results and studied the impact of the horizontal resolution in model during different weather process in complicated topography area in Tibet, the mean wind observation data from wind tower and high-resolution numerical model data were be used, the characteristics of the mean wind and the turbulent kinetic energy (TKE) in the near-surface boundary layer around the region of the wind tower point and comparison point were analyzed. The results showed that the mean wind observation data were a well consistency. With time variations, the mean value of ten minute wind speed were an upward trend over time during different strong wind weather systems. The air flow and the spatial distribution of TKE were consistent around the region of the wind tower point and comparison point. The air flowed from high elevation areas (mountain ridge) to the low elevation areas (mountain valley) during different resolution numerical model data. Comparative analysis of different resolutions simulation results, the higher-resolution simulation result showed more clear in the characteristics of the air flow. The correlation had increased considerably between the different times of the mean value of the ten minute wind speed or TKE on the vertical layers, as well as the bias was decreased.
