Análise Climática da Microrregião do Litoral norte da Paraíba

Abstract

The Brazilian Northeast as well as the state of Paraíba has different precipitation regimes, and it is in this context that it is necessary to monitor the climatic indices in order to provide information on the dry and rainy periods in the microregion of the North Coast of Paraíba, in order to provide proper management of water resources. The methodology used for the evaluation of dry and rainy periods was the rainfall anomaly index (IAC), which showed the rainiest months that occur from March to July and the driest August to May. We used 18 stations distributed along the micro-region of North Coast with 20 years in which 10 showed positive anomalies and 10 showed negative anomalies. It was also observed that dry and rainy periods occur in the same amount and their intensities vary with extreme years. This work also includes the weather spatial micro, which showed that the eastern portion was the most benefited with precipitation being an area that receives a greater influence on the ocean, and the second the western portion of the micro-region was the least favored, with a less precipitation. Finally were also made projections of increased and reduced precipitation in 20% of the value obtained from the time series as recommended by the IPCC (Intergovernmental Panel on Climate Change), so it was possible to project future climate variations in the micro-region in relation your fluid intake, in order to provide an adequate management of water resources for micro, considering its value for maintaining life.
