The influence of urban features on air temperature distribution.

The knowledge of the influence of urban features on air temperature distribution in a city is very important, especially considering the population increase worldwide and the impact of urban climate on human health. The aim of this study is to investigate the distribution of air temperature in the city of Florence during the summer and to evaluate its relationship with building height, urban density and presence of trees. A significant positive relation between minimum air temperature and mean height of buildings and urban density was found throughout the entire summer period especially during the hottest months (July and August).
