| 摘 要： | 利用1971—2001年青藏高原东边缘地区12个气象台站风资料,分析了影响极值风速的主要因子,通过对地形的参数化处理,建立了极值风速随海拔高度和地形参数变化的拟合模型,可推算该地山区的极值风速,并利用山区临时观测资料对拟合模型进行了检验。结果表明,利用引入地形参数所建立的极值风速拟合模型来推算山区极值风速具有一定的可行性。

| Abstract: | Based on the wind data of 12 meteorological stations on the eastern edge of Qinghai-Xizang Plateau from 1971 to 2001, the main factors for influlencing maximum wind speed are analyzed,the fitted model of maximum wind speed based on the elevation above sea level and terrain parameters is established throught the processing the terrain parameter,the maximum wind speed of the adjacent mountains can be reckoned,the fitted model is tested using the interim observational data of mountain area. The result shows that the fitted model of maximum wind speed established by introduced terrain parameters to reckone the maximum wind speed of mountain area has certain feasibility. |
