| Popis: | In the present study, the wind data during two synoptic processes observed by the surface wind tower in the Tibetan Plateau and the high spatial resolution model data simulated by CALMET were be evaluated, the horizontal and vertical distribution characteristic of the model wind data around the region of the wind tower point and the reference point were be analysed. Results showed that the wind observation data during the two processes in the nearsurface boundary were a well consistency. The horizontal distribution of the wind fields were consistent at the moment of the maximum wind speed during the two processes. The trend of the ten minute mean wind speed were upward with time variations. The air was flowed from the mountain ridge to the mountain valley over the complex region. The vertical distribution of the wind speed had more relevant that the correlation coefficient were 0.6811(α = 0.05) in the observation tower point and 0.8304 (α = 0.05) in the reference point between 16:00 pm Jan 30th and 16:00 pm Jan 31st. The advantages of using the advanced numerical models will be reflected over the extremely complex underlying terrain where the lack of observation stations. |
