Résumé
Brazilian semi-arid region, one of the most populated in the world, have a population of approximately 23 million inhabitants distributed in 1135 municipalities, with 62% in urban areas and 38% in rural areas. Assuming that the semi-arid climate naturally imposes water restrictions that can generate problems for the growth of the municipalities and assuming that the urbanization process can promote changes in the thermal field, generating temperature increase, the main goal of this research was to evaluate the hydroclimate and hygrothermal conditions of the city of Caicó/RN/Brazil, in order to offer a backup for municipal management and for society actions, which combined with the climate elements, are closely related to the population’s quality of life. Hydroclimatological analysis were performed on the state of Rio Grande do Norte (historical data 1963-2013) and on the city of Caicó, using rainfall (historical data 1911-2013), evaporation and evapotranspiration (historical data 1996-2013) data for statistical and geostatistical analysis and to apply climatic indices. Air temperature, relative humidity and wind speed data from Caicó (historical data 1996-2010) were collected from both climate normals and automatic thermo-hygrometers (period 05/05/2016-05/06/2016) installed around the city during this study period. For hygrothermal analysis, statistics and bioclimatic levels of human comfort were applied. The results express the climatic peculiarities of this city, its behavior and the main hydroclimate and hygrothermal characteristics showing how human activities can interfere with the local area to either improve or worsen the land-surface atmosphere interaction at a local level.
