Le mappe termiche della città di Firenze: la ricerca alla base delle strategie di adattamento degli estremi termici in città

The growth of urban populations means that most people will experience urban climate, that is significantly different from the rural one. Urban climate is a very complex field of study because of the great number of characteristics that affect weather variables in the urban environment and because of the different kind of morphologies and materials used in cities all over the world. There is a need to increase the climatic knowledge of urban areas all over the world and to translate it into a planning language in order to facilitate the design of more sustainable cities. The aim of this work is to show how thermal maps can be used by urban planners and policymakers to take action towards urban temperature mitigation. A network of air temperature sensor was used to quantify the thermal variability of Florence and to analyze the relationship between air temperature and some urban indicators, such as green cover ratio, street cover ratio and building volume. All those studies were used to create different kind of thermal maps of Florence. These maps can have several applications, such as phenology, urban planning and human health: for example these maps can be used to create other maps, such as biometeorological maps for plant flowering, or biometeorological maps for human health studies used to classify areas at higher risk during the heat waves or cold spells.
