英文摘要	This article aims at studying the characteristics of high-altitude wind at the Ali Observatory on the western Tibetan Plateau, as the high-altitude wind has been put forward as a critical parameter for site evaluation, especially for adaptive optics. We have run a meso-scale numerical weather research and forecasting (WRF) model in three nested domains with different horizontal resolutions, centred at the Ali Observatory; the model results with the highest horizontal resolution of 1 km and temporal resolution of 0.5 h are presented, and also statistical analyseis of vertical wind profiles and 200 hPa wind speed are performed. Moreover, comparisons of wind speeds obtained from model and radiosoundings are presented; as the vertical resolution has been proved to be key to the estimation of optical turbulence with meso-scale models, the vertical resolutions are both set to 50 m for wind profiles, which reveals a high level of agreement and provides a useful tool for site assessment. The results prove the good character of the high-altitude wind over the Ali region, especially in summer half year, with a yearly median 200 hPa wind speed of 33.6 ms(-1) in 2016, and also provide proof of the potential advantage of the Ali Observatory for adaptive optics. Furthermore, we certify that meso-scale models can offer dependable estimation of high-altitude wind over the Tibetan Plateau; the wind simulations provided by the WRF model will be of great benefit for adaptive optics, which also provides the vertical distributions of C-N(2) and tau(0) above astronomical observatories.
