摘要
白鹤滩水电站坝区易形成一种与平原地区截然不同的局部环流-山谷风,风速较大,对工程施工带来较大影响。分析了坝址新田气象站2012年的气象资料,同时与离坝址最近的巧家、宁南县气象站资料对比,归纳出坝区特有的灾害性大风的日、月、季节变化特征。为下一步结合天气形势分析,找出灾害性大风短期或短时预报因子提供了基础。
Being quite different with local circulation in plain areas, the gale with higher speed in the dam area of Baihetan Hydropower Station occurs frequently and exerts a significant influence on the project construction. Through analysis on the data of Xintian meteorological station in 2012 and comparison with those of the meteorological stations nearest to the dam site in Qiaojia and Ningnan counties, the paper summarizes the characteristics of daily, monthly and seasonal variations of the specific disastrous gale in the dam area. The results provide a basis for identifying short - term forecasting factors together with the analysis of synoptic situation.
