Abstract

The aim of this study was identify and characterize homogeneous environments based on precipitation observed in Mato Grosso do Sul State, Brazil. For this, data from different climatic stations located in Mato Grosso do Sul and its surroundings were used. By cluster analysis, using a hierarchical method based on Euclidean distance as dissimilarity measure and sum of squares as a criterion for fusion (Ward´s method) were identified three homogeneous environments in Mato Grosso do Sul. These homogeneous environments were characterized evaluating their basic statistics and using new cluster analysis, this time evaluating the behavior of the decendial rainfall in each group separately.
