Avaliação espaço-temporal da precipitação da microrregião do brejo paraibano

Abstract

Rainfall in Northeast of Brazil presents a great variability due to different producing systems of active rainfall in the regionand due to the fact that this region is located insemi-arid area of Brazil.In this case, it was applied the Rain Anomaly Index (RAI) in order to evaluate the spatiotemporal weather in the Wetland region of Paraiba, and to observe the intensity of dry and wet periods of the micro-region.It was noticed that in each year there are two distinct periods: a wet, from February to August and a dry one, which runs from September to January.In spatial climatology, we can observe a better distribution of rainfall between the months of March to August, with June having the best spatial distribution, being more evident a greater concentration of rainfall in the west/northwest of the micro-region.The wetland micro-region of Paraiba has a great variability of rainfall and the period from February to August is the best time for planting and water supply in the area.
