Caracterização da temperatura do ar no estado de Goiás e no Distrito Federal

Abstract

The study of air temperature is of paramount importance with regard to the planning of human activities, with large or small scale and impact. Thus, this study aimed to perform a spatial characterization of temperature in the state of Goiás and Federal District. For this, it was used temperature data from 47 meteorological stations in and around the study area. These stations and their data were converted to vector point and worked in a GIS environment. In spatial distribution of data across the study area was used interpolation method Top Raster. It was found that, in the State of Goiás and the Federal District, the hottest month of the year is October and are milder in June and July with temperature range between the warmest and the coldest of 4.5°C. The hottest region was presented to the Northwest Goias, local lower altitude and lower temperature regions were among the municipalities of Goiânia and Anápolis around Brasilia and southwest of the Goiás State, higher altitudes, showing the influence of relief under the conditions presented by this climate variable. It was found also the influence of the use and occupation of land in the temperature variation in the state of Goiás and Federal District.
