| 摘 要： | 应用2008年天津市14个自动气象站逐小时资料和6h一次的地面常规资料，对天津城市热岛效应的时空特征进行了分析，结果表明：天津市热岛强度的日变化、月变化和年、季特征显著，且天津市热岛强度与城郊站的选择方法有密切关系。通过多元线性回归方法，分析了天津市热岛强度与云量、云高、风向、风速和相对湿度这5种气象要素的相关性，发现风速是影响天津城市热岛效应的显著气象因子，但总体而言气象要素对天津城市热岛效应的影响相对较小。

| Abstract: | In this paper, the temporal and spatial characteristics of urban heat island effect in Tianjin city in the year 2008 were analyzed by using the observation data and the 6 h ground general data from 14 automatic meteorological stations in Tianjin. The results showed that the urban heat island effect in Tianjin not only had significant diurnal, monthly, seasonal and annual variation characteristics, but also was closely related to the method to choose urban and suburban stations. Finally, the relationship be- tween urban heat island intensity and cloud, wind, humidity was analyzed by using the multiple linear regression analysis method. It was found that the wind speed was a dominant meteorological factor, but the overall impact of the meteorological elements on the urban heat island effect in Tianjin was relatively limited. |
