Distinguished torsion response will occur when the direction of wind is out of perpendicular to the building surface, even for the symmetric structure.

此外，迎风角的微小改变，对建筑物的受力情况影响很大，即使是对称结构，当风向与建筑物表面不垂直时，扭转效应也非常明显。

After the surface pressure characteristics of the surface pressure distribution that the mechanism of wind-resistant design to determine the structure is not conducive to regional and wind direction.

经表面风压特性分析指出表面风压分布的机理，分析确定不利于结构抗风设计的区域及风向角。

The higher temperature centers appear in the downwind direction by the effects of surface wind fields. Surface temperature and PBL height are both closer to observation values.

近地面气温和边界层高度均更贴近实测值。由上述结果引出讨论了下垫面土地利用分类在模式模拟中的重要地位及其他可能原因。
