摘要

The characteristics of a region and its environmental changes are directly associated with the characteristics of the climate and the changes that occur in it. The importance of the study of the climate of a region is widely known in agriculture, by the size of the impact that the climate has on the productivity and final quality of the products. From the studies of these spatial and temporal changes in climatic and environmental information, excellent results have been obtained in understanding the variability of atmospheric phenomena that occur throughout. The objective of the present work was to perform the climatic characterization of the Machado-MG region, analyzing data collected on the elements of the climate, applying methodologies that allow its spatialization, from geotechnology tools, more precisely, the techniques of interpolation and manipulation of spatial data in the Geographic Information Systems (GIS) environment. For this purpose, it has been used the climatic data obtained from meteorological stations of the National Institute of Meteorology-INMET, located in the state of Minas Gerais, referring to the monthly and annual averages of a historical series of 55 years (1961-2015). The results obtained allowed to characterize the climate of the municipality, which presented an average temperature around 15°C to 25°C and with average rainfall between 100 - 200 mm in the rainiest periods. The relative humidity of the air presents throughout the year values in the average of 60% to 80%. From the spatialization maps of temperature, precipitation and relative humidity of the air, it becomes possible to analyze the spatial behavior of the climatic elements and thus to have the perception of the climate dynamics in the region.
