Decadal precipitation in the municipal area of Paudalho - Pernambuco, Brazil

The objective is to carry out a climatological analysis of decadal precipitation and its historical comparisons using the historical series of rainfall from 1967 to 2015, which can contribute to decisions in sectors such as the economy, agriculture, irrigation, energy production, water resources, agronomic engineering, agricultural engineering, irrigation fire department, civil defense and government decision makers in case of extreme precipitation events that may occur in the future. The data were acquired from the Pernambuco Water and Climate Agency of the state of Pernambuco in the period from 1967 to 2015, for which the calculations of basic statistics were applied to define the decades of studies and their respective averages. The inter-neighborhood variability of rainfall distribution and local activities in conjunction with the active meteorological factors contributed or did not contribute to agricultural productivity, human and animal storage and supply. The study can be a tool for planning and actions aimed at the best way to manage water resources using capture and storage systems (taking advantage of the first months with high precipitation rates) and avoiding the problem of water scarcity.
