Resumo: This article discusses desertification processes in the semi arid climates atNortheast Brazilian Region, by use of temporal series method. The resultsindicates that 49,7% of the rainfall series data showed increase tendencyconfiguring indistinct regional distribution presenting, however, more incidenceat Rio Grande do Norte, Paraíba e Pernambuco states and, principallyin the area well-known between Borborema plateau and Apodi meseta andits meridian prolonged. This fact indicates that regional mean rainfall followthe tendency of increase detected at the last decades, probably associatedwith greenhouse effect. By the other side, 50,3% of the temporal seriesdata showed stable or decrease tendency. The first one with uncharacterizedgeographical distribution and the second occurred in four small areassignalized as possible desertification areas.

O quadro geral da análise indicou 49,7% das sériesapresentando tendência crescente nas médias pluviométricas, configurandouma distribuição geográfica indiferenciada, apresentando, contudo,incidência maior no Rio Grande do Norte, Paraíba e Pernambuco, sobretudono espaço compreendido entre o reverso continental da Borborema e chapadado Apodi e seus prolongamentos meridionais. Tal constatação indicaque a precipitação em nível regional acompanha a tendência de elevação damédia pluviométrica que vem sendo registrada nas últimas décadas, presumivelmenteassociada ao agravamento do efeito de estufa. Por outro lado,50,3% revelaram tendência estável ou decrescente, as primeiras, com distribuiçãogeográfica mal caracterizada, ao passo que as segundas agruparam-se em quatro manchas, sinalizadoras de indícios de desertificação localizada.Universidade Federal do ParanáBueno Conti, José2005-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://revistas.ufpr.br/revistaabclima/article/view/2522610.5380/abclima.v1i1.25226Revista Brasileira de Climatologia; v. 1 (2005)2237-86421980-055X10.5380/abclima.v1i1reponame:Revista Brasileira de Climatologia (Online)instname:ABClimainstacron:ABCLIMAporhttps://revistas.ufpr.br/revistaabclima/article/view/25226/16925https://revistas.ufpr.br/revistaabclima/article/view/25226/16926info:eu-repo/semantics/openAccess2014-11-29T20:00:01Zoai:revistas.ufpr.br:article/25226Revistahttps://revistas.ufpr.br/revistaabclima/indexPUBhttps://revistas.ufpr.br/revistaabclima/oaiegalvani@usp.br || rbclima2014@gmail.com2237-86421980-055Xopendoar:2014-11-29T20:00:01Revista Brasileira de Climatologia (Online) - ABClimafalse
