摘　　要：利用马鞍山市1981~2010年的气象数据计算选取典型气象年,绘制了不同季节及全年的风频风速玫瑰图,并在此基础上分析了风速对热岛效应的影响。研究发现,马鞍山市典型气象年全年静风较少,主导风向相对较为明显,盛行东风,除冬季主导风向为西西北风外,其余季节及全年的主导风向均为东风,全年主导风向的风速皆小于2 m/s。马鞍山市近30年风速呈下降趋势,城市化后的风速较城市化前风速有显著降低,通过回归方程拟合可发现风速与热岛效应存在明显的负相关,相关系数最高可达0.84。Based on the meteorological data of Ma’anshan City from 1981 to 2010,the typical meteorological years were selected,the wind frequency and wind speed roses in different seasons and throughout the year were drawn,and the influence of wind speed on heat island effect was analyzed.The results show that in typical meteorological years,there is less quiet wind and the dominant wind direction is relatively obvious.Easterly wind prevails.Except for the northwest wind in winter,easterly wind is the dominant wind direction in all seasons and throughout the year,and the wind speed of the dominant wind direction is less than 2 m/s.In recent 30 years,the wind speed in Ma’anshan city has a downward trend,and the wind speed after urbanization is significantly lower than that before urbanization.Through regression equation fitting,it can be found that there is an obvious negative correlation between wind speed and heat island effect,and the correlation coefficient is up to 0.84.
