A análise do regime pluvial importa para conhecimento da dinâmica hídrica, além de ser um instrumento indicador de tendências climáticas e possíveis anomalias. Foram utilizados dados de séries históricas de sete estações pluviométricas da área no período de 1984/85 a 2018/19. Utilizou-se os métodos de Dupla Massa e Regressão Linear Múltipla para verificar a homogeneidade dos dados e completar os dados anuais faltantes através do R². Realizou-se o cálculo das médias pluviométricas por estação, a partir do método da média aritmética. Em seguida, utilizou-se o método dos Polígonos Thiessen para os cálculos das áreas de influência e da precipitação média, além de determinar a estação mais representativa da área. Esboçou-se o comportamento pluviométrico centenário com a análise de dados da estação Mineração Morro Velho, com mais de 130 anos registrados, observando-se ciclos de aproximadamente 9 anos, afora uma redução a partir de 2013/14. A análise da pluviometria em relação aos dias de chuvas dos ciclos indicou a diminuição da pluviometria total, por revelar o decaimento dos dias de chuva.Located in the east portion of the Quadrilátero Ferrífero and south of the metropolitan region of Belo Horizonte, Moeda syncline has water relevance for the region and comprises 9 municipalities. The area rainfall study is necessary to understand its water dynamics, in addition to being an indicator of climate trends and possible anomalies. The data from a historical series of rainfall stations in the hydrological period from 1984/85 to 2018/19 was used. The Double Mass and Multiple Linear Regression methods were used to verify the data homogeneity and complete the missing annual data through the R². The calculation of rainfall averages per season was executed using the arithmetic average method. Then, Thiessen Polygon method enabled the calculation of the areas of influence, the average precipitation of the region, in addition to the most representative station. The centenary rainfall behavior was sketched from the data analysis of the Mineração Morro Velho station, which has more than 130 years of registers, observing 9-year cycles, in addition to a reduction from 2013/14. The rainfall analysis concerning the cycles rainy days indicated a decrease in total rainfall, as it reveals the decay of rainy days.porUniversidade Federal de Minas GeraisUFMGBrasilIGC - DEPARTAMENTO DE GEOLOGIAAlemurHidrometeorologiaAnálise de regressãoHidrogeologiaDupla massaRegressão linear múltiplaPolígonos de ThiessenCaracterização pluviométrica do Quadrilátero Ferrífero na região do Sinclinal Moeda – Minas GeraisPluviometric characterization of Quadrilátero Ferrífero in the region of Moeda Syncline - Minas Geraisinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://periodicos.ufop.br/alemur/article/view/5116Camila Evellyn CruzIsabela Sabadini Henriques CaetanoAna Clara Vieira MotaJulia Jordânia FerreiraJoana Victoria Fernandes de SouzaLeila Nunes Menegasse VelásquezRodrigo Sergio de Paulaapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/59764/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALCaracterização pluviométrica do Quadrilátero Ferrífero na região do Sinclinal Moeda – Minas Gerais.pdfCaracterização pluviométrica do Quadrilátero Ferrífero na região do Sinclinal Moeda – Minas Gerais.pdfapplication/pdf1043447https://repositorio.ufmg.br/bitstream/1843/59764/2/Caracteriza%c3%a7%c3%a3o%20pluviom%c3%a9trica%20do%20Quadril%c3%a1tero%20Ferr%c3%adfero%20na%20regi%c3%a3o%20do%20Sinclinal%20Moeda%20%e2%80%93%20Minas%20Gerais.pdfe4cf87d352a12553794b060180329126MD521843/597642023-10-19 16:57:05.984oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-10-19T19:57:05Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
