Silva, Walquiria Marins [UNESP]Simões, Silvio Jorge Coelho [UNESP]2016-03-022016-03-022014International Journal of Geosciences, v. 2014, n. 5, p. 408-417, 2014.2156-8359http://hdl.handle.net/11449/135495The emphasis in this research is to evaluate the spatial distribution of the precipitation using a geostatistics approach. Seasonal time scales records considering DJF, MAM, JJA e SON periods performed the analysis. Procedures to evaluate the variogram selection and to produce kriging maps were performed in a GIS environment (ArcGIS®). The results showed that kriging method was very suitable to detect both large changes in the whole area as those local small and subtle changes. Kriging demonstrated be a powerful statistical interpolation method that might be very useful in regions with great complexity in climatology and geomorphology.408-417engSpatial RainfallSemivariogramKrigingHydroclimatologic analysisSpatial intra-annual variability of precipitation based on geostatistics. a case study for the Paraiba do Sul Basin, southeastern BrazilArtigo10.4236/ijg.2014.54039Acesso abertoISSN2156-8359-2014-2014-05-408-417.pdf7371537941854293
