Resumo: Rainfall variability is a striking feature in the semi - arid region, not only in annual totals, but also in quantity and spatial distribution. In order to contribute to the understanding of extreme precipitation events in the semi - arid region of Paraíba, it was identified years of extreme events in the Sertão Paraíba micro - region, using the rainfall anomaly index (IAC). The data used came from the CPC (Climate Prediction Center), a center belonging to the NCEP (National Centers for Environmental Prediction), covering the period 1979-2013. The results show a very homogeneous temporo-space distribution in relation to the extreme events, that is, the rainy or dry years, when they occur reaches the entire microregion. It was observed that in the annual panel a very small precipitation period, it is considered the rainy season and after this period a drastic decrease in precipitation occurs. Of the 35 analyzed years of precipitation, it was verified that 19 years presented rainfall below the climatological average (54.3%) and 16 years with precipitations above the average (45.7%).The contribution of the months that do not compose the rainy season to the Sertão Paraibano microregion (May to January - 9 months), presented in a significant way in the rainy events, however, for the dry events had no contribution. The spatial variation of the precipitation in the region for both the climatology and the compositions of the years selected as dry and rainy, shows a distribution in the east-west direction, with high amplitudes, proving the spatial variation.

Com o objetivo de contribuir para o entendimento dos eventos extremos de precipitação na região semiárida da Paraíba, foi identificado anos de eventos extremos na microrregião do Sertão paraibano, utilizando o Índice de Anomalia de Chuva (IAC). Os dados utilizados foram provenientes do CPC (Climate Prediction Center), centro pertencente ao NCEP (National Centers for Environmental Prediction), compreendendo o período de 1979-2013. Os resultados mostram a distribuição têmporo-espacial bastante homogênea em relação aos eventos extremos, ou seja, os anos chuvosos ou secos, quando ocorrem atingem toda a microrregião. Observou-se que no painel anual um período bem pequeno de precipitação, considera-se o período chuvoso e após este período percebe-se que ocorre uma diminuição drástica na precipitação. Dos 35 anos analisados de precipitação, verificou-se que 19 anos apresentaram precipitações abaixo da média climatológica (54,3%) e 16 anos com precipitações acima da média (45,7%). A contribuição dos meses que não compõe o período chuvoso para a microrregião do Sertão Paraibano (maio a janeiro), apresentou-se de forma significativa nos eventos chuvosos, entretanto, para os eventos secos não teve nenhuma contribuição. A variação espacial da precipitação na região tanto para a climatologia, quanto para as composições dos anos selecionados como secos e chuvosos, apresenta distribuição no sentido Leste-Oeste, com amplitudes altas, comprovando a variação espacial.Editora Verde2017-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfimage/pngapplication/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenthttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/493810.18378/rvads.v12i4.4938Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 12 No. 4 (2017); 748 - 755Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 12 Núm. 4 (2017); 748 - 755Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 12 n. 4 (2017); 748 - 7551981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/4938/4799https://www.gvaa.com.br/revista/index.php/RVADS/article/view/4938/9180https://www.gvaa.com.br/revista/index.php/RVADS/article/view/4938/9182https://www.gvaa.com.br/revista/index.php/RVADS/article/view/4938/9183Copyright (c) 2017 Jaricélia Patrícia de Oliveira Sena et al.info:eu-repo/semantics/openAccessSena, Jaricélia Patrícia de OliveiraLucena, Daisy BeserraRibeiro, George do Nascimento2021-06-14T13:14:39Zoai:ojs.gvaa.com.br:article/4938Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:20.023283Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false
