ANÁLISE DO REGIME PLUVIOMÉTRICO DA MICRORREGIÃO GEOGRÁFICA MEIA PONTE, ESTADO DE GOIÁS.

Abstract

Knowledge of climatic elements, in particular the rainfall is of major importance to the productive sectors of society and for the survival of man. The oscillation of such elements leads necessarily to a variability in daily activities. The aim of this study was to analyze the rainfall for geographic micro Meia Ponte. The data were provided by the National Water Agency (ANA), National Institute of Meteorology and (INMET) and the Brazilian Institute of Geography and Statistics (IBGE). For spatial data processing and making cartographic products was used QGIS 2.14.3 program, through which data from 29 rain gauge stations and a weather station were georeferenced to cartographic projection in geographic coordinates, WGS 84. The method interpolating the data used was the Inverse Distance Weighted. The statistic was based on data from only 14 rainfall stations present in the micro region. The dry season corresponds to the months of May to August and the rainy season corresponds to the months of September to April. The average rainfall in the dry and rainy periods, maximum annual average rainfall and average total annual precipitation for the micro Meia Ponte, were respectively 60.79 mm, 1379.52 mm, 79.19 mm and 1440.31 mm, the results show a negative trend for all characteristics except the maximum average annual rainfall. The characterization of local rainfall and its tendency is constituted as an important tool for planning agricultural activities and projects linked to other activities that make use of climate data.
