Resumo: As a result of the change in the pattern of atmospheric circulation caused by weather phenomena, in some areas of Brazil extreme droughts occur, in others, torrential rains. Such aspects make it possible to infer about the socio-environmental and economic problems resulting from these phenomena. In view of this, this work sought to analyze the relationship of El Niño Southern Oscillation (ENSO) events with rainfall anomaly index (IAC). The historical series of rainfall used were from the Santarém station (1969 to 2019) and Nova Maringá station (1984 to 2020), classifying the ENSO events within these periods, through the Niño Oscillation Index (ION). With this, it was observed from the IAC classification, that the strong phenomena as extremely dry and extremely humid, coincided with the classification of the ENSO phenomena of El Niño and La Niña for Santarém station. The El Niño and La Niña phenomena have little evident effect on the number of rainy days for the Maringá station. Through the study conducted to analyze the monthly and annual variations of rainfall through the IAC, it was shown that these occur in most cases under the influence of the more intense ENSO phenomenon, causing rain in that region. Comparing the results found for the south of the basin (Nova Maringá) and for the north (Santarém), it is observed that the influence of ENSO events is stronger for the northern region of the Tapajós River Basin (BHRT).

Tales aspectos permiten inferir sobre los problemas socioambientales y económicos derivados de estos fenómenos. En vista de esto, este trabajo buscó analizar la relación de los eventos de El Niño Oscilación del Sur (ENOS) con el índice de anomalía de lluvia (IAC). Las series históricas de lluvias utilizadas fueron de la estación Santarém (1969 a 2019) y la estación Nova Maringá (1984 a 2020), clasificando los eventos ENSO dentro de estos períodos, a través del Índice de Oscilación del Niño (ION). Con eso, se observó a partir de la clasificación del IAC, que los fenómenos fuertes como extremadamente seco y extremadamente húmedo, coincidieron con la clasificación de los fenómenos ENOS de El Niño y La Niña para la estación de Santarém. Los fenómenos de El Niño y La Niña tienen un efecto poco evidente en el número de días de lluvia para la estación de Maringá. A través del estudio realizado para analizar las variaciones mensuales y anuales de las precipitaciones a través del IAC, se demostró que estas ocurren en la mayoría de los casos bajo la influencia del fenómeno ENSO más intenso, provocando más o menos lluvias en esa región. Comparando los resultados encontrados para el sur de la cuenca (Nova Maringá) y para el norte (Santarém), se observa que la influencia de los eventos ENSO es más fuerte para la región norte de la cuenca del río Tapajós (BHRT).Como resultado da alteração do padrão de circulação atmosférica causada por fenômenos climáticos, em algumas áreas do Brasil ocorrem secas extremas, em outras, chuvas torrenciais. Tais aspectos permitem inferir a respeito das problemáticas socioambientais e econômicos resultantes destes fenômenos. Diante disto, este trabalho buscou analisar a relação dos eventos El Niño Oscilação Sul (ENOS) com índice de anomalias de chuva (IAC). As séries históricas de precipitação pluviométrica utilizadas foram da estação Santarém (1969 a 2019) e estação Nova Maringá (1984 a 2020), classificando os eventos ENOS dentro destes períodos, através do Índice de Oscilação do Niño (ION). Com isso, observou-se a partir da classificação do IAC, que os fenômenos fortes como extremamente seco e extremamente úmido, coincidiram com a classificação dos fenômenos ENOS de El Niño e La Niña para estação Santarém. Os fenômenos El Niño e La Niña pouco causa efeitos evidentes no Número de dias de chuvas para a estação Maringá. Através do estudo realizado para analisar as variações mensais e anuais das precipitações pluviais através do IAC, mostrou-se que estas ocorrem na maioria dos casos por influência do fenômeno ENOS mais intensos, fazendo chover mais ou menos naquela região. Comparando os resultados encontrados para o sul da bacia (Nova Maringá) e para o norte (Santarém), observa-se que a influência dos eventos ENOS é mais forte para a região norte da bacia Hidrográfica do Rio Tapajós (BHRT).Research, Society and Development2022-12-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3800410.33448/rsd-v11i17.38004Research, Society and Development; Vol. 11 No. 17; e169111738004Research, Society and Development; Vol. 11 Núm. 17; e169111738004Research, Society and Development; v. 11 n. 17; e1691117380042525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/38004/32174Copyright (c) 2022 Luandra Caroline Veloso Ferreira; Gabriela Rosa Batista; Carlos Eduardo Aguiar de Souza Costa; Sarah Brasil de Araújo de Miranda; Gustavo Francesco de Morais Diashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFerreira, Luandra Caroline Veloso Batista, Gabriela Rosa Costa, Carlos Eduardo Aguiar de SouzaMiranda, Sarah Brasil de Araújo de Dias, Gustavo Francesco de Morais 2022-12-28T13:53:48Zoai:ojs.pkp.sfu.ca:article/38004Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:51:56.530955Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
