摘　　要：利用2021—2023年绍兴轨道交通高架路段沿线5个气象观测站的数据,对高架路段平均风特征进行分析,并通过Pearson相关性分析研究温度对风速的影响。结果表明,绍兴轨道交通高架路段沿线平均风速的时间变化具有相似性。季节变化除江南外,由大到小依次为夏季、春季、秋季和冬季;月变化基本在7月达到峰值;日变化呈“一峰一谷”型,风速在午后到傍晚最大,在日出前后最小。高架路段沿线平均风向的空间分布具有差异性,但主要集中在第二、三象限。温度会对高架路段沿线风速造成影响。除清风外,其余各站的平均风速与平均温度之间具有相关性;5个气象观测站的极大风速与平均温度之间具有相关性,均呈正相关。Using data from five meteorological observation stations along the elevated section of Shaoxing Rail Transit from 2021 to 2023,the average wind characteristics of the elevated section were analyzed,and the impact of temperature on wind speed was studied through Pearson correlation analysis.The results show that:The temporal changes of average wind speed along the elevated section of Shaoxing rail transit are similar.Except for Jiangnan,the seasonal changes are summer,spring,autumn,and winter from large as to small average speed;the monthly change basically reaches its peak in July;the daily change is in the form of"one peak and one valley",with the wind speed being the largest from afternoon to evening and the smallest around sunrise.The spatial distribution of the average wind direction along the elevated section is different,but it is mainly concentrated in the second and third quadrants.Temperature affects the wind speed along the elevated section.Except for the clear wind,there is a correlation between the average wind speed and the average temperature at the other stations;there is a positive correlation between the maximum wind speed and the average temperature at the five meteorological observation stations.
