摘　　要：通过对绿色建筑室外风环境模拟案例进行调研发现,存在室外风气象数据源选取不统一、主导风参数定义不明确、冬夏季及过渡季划分模糊不清等问题,致使风环境模拟结果很难真正、科学地指导建筑设计。为此,本文基于两套代表性气象数据库及两种典型季节划分方法进行风参数条件不确定影响分析,研究发现不同气象数据源和不同季节划分法下室外主导风向及风速存在一定差异,相比而言气象数据源的影响更为显著,建议行业尽快统一规定各地室外气象数据源以及采用侯温法划分季节,有助于规范化建筑室外风环境模拟工作,促进绿色建筑健康发展。By surveying cases related to wind environment simulation of green buildings, some important problems are found, such as the different meteorological data source, unclear definition of local dominant wind parameter and indistinct season division, which result in the poor guidance of simulation results. Therefore, this paper analyzes the uncertain wind parameters＇ impact on wind environment simulation based on two typical weather database and season division methods. It is found that different weather database and season division methods make a difference on dominant wind direction and speed and the former＇ s impact is significant. The unified weather database by local standard and climate temperature based season division method are suggested. The study helps to guide and regulate the standardization processes of wind environment simulation and promote the development of green buildings.
