Variabilidade no regime pluvial em duas mesorregiõres da Paraíba e sua relação com o fenômeno EL Niño Oscilação Sul.

Abstract: A B S T R A C TThe El Niño Southern Oscillation (ENSO) is always associated with the occurrence of rain and drought. The study aimed to determine the possible association in the annual variability of the rainfall regime in the Sergão and Borborema regions of Paraíba. It was used the monthly rainfall series, the 1961-2015 periods, assigned by the Executive Agency for the Management of the State of Paraíba Waters (EFSA), these geographical clippings. The rainfall data were analyzed by statistical climatologicall… Show more

“…In 2008, the municipality presented in this research was influenced by La Niña with strong intensity (Almeida & Medeiros, 2017). The period between 2011 and 2012 is considered as the one with the greatest rainfall deficit in Northeast region in the last 30 years, causing severe water shortage and increase in food prices (Leivas et al, 2014).…”

“…The adjustment of the theoretical space-time variogram model was made by using the weighted least-squares (WLS) method, which replaces R(ω) with the diagonal matrix W(ω). The elements of W(ω) were obtained from Equation (6). Thus, using the weights given in this Equation 7, the WLS method is given by:…”

“…In this region, it is common to observe high rainfall indices in a particular location and no record of rain in its surroundings [5]. The state of Paraíba, located in this region, presents the same characteristics, with periods of drought in rainy seasons and behavior different from the precipitation between the mesoregions that constitute the region [6]. Consequently, Paraíba presents a problem concerning the spatiotemporal variability of rainfall.…”

“…Estudos publicados sobre a influência do ENOS no regime de chuvas no Brasil envolveram as regiões Sul e Sudeste (Cera e Ferraz, 2015;Lima e Nunes, 2018), o Norte e a parte setentrional do NEB (Araújo et al, 2013;Nóbrega et al, 2016;Almeida e Medeiros, 2017;Pinheiro et al, 2018;Salgueiro et al, 2018 2019A RHAL apresenta quatro climas: árido, semiárido, úmido e subúmido, sendo uma região com forte incidência de radiação solar. A evapotranspiração anual oscila de 1400 mm em Salvador e Aracaju a menos de 900 mm na Chapada Diamantina, conforme apresentado na Figura 2.…”
