Clima urbano em cidades de pequeno porte: o caso de Saudades-SC

Abstract

Over time, cities have undergone important transformations to adapt to the growing population. The change in land use promoted by the expansion of the urban fabric added artificial elements in such a way that the cities began to unbalance and this reflected in the local climate. If, at first, large cities were the focus of studies, later, small cities began to draw attention to the observation that they also present imbalances in relation to the local climate. For this reason, studying them is always a novelty, due to the lack of work in these cities. In this sense, the objective of this work was to analyze the interaction between urban conditions and the local climate in the city of Saudades, west of the state of Santa Catarina. In this context, the collection of temperature data obtained through a mobile transect of 3.6 km in length that crosses the urbanized area of the municipality. Collections were carried out on at least five different days, considering the active atmospheric system and at three times (9:00 am, 3:00 pm and 9:00 pm), which represent the morning, afternoon and night periods and which correspond to the official times of meteorological data collection. in conventional stations in Brazil. The data were analyzed through the construction of graphs representing the transect in order to identify representative thermal changes to the point of attesting possible occurrences of islands of heat/cooling.
