Resumo: The variability of Monthly maximum and minimum temperatures of 265 stations components of INMET’s Meteorological Database for Teaching and Research (BDMEP) in the last 50 years was related to variations in the Oceanic Niño Index from NOAA Climate Prediction Center by training an artificial neural network. The results showed that El Niño contributed to the increase of the maximum and minimum temperatures while the reverse occurs in La Niña events, except for the Amazon region. The impact of ENSO (El Niño-Southern Oscillation) in the country is more present in winter and spring. Some locations were chosen to demonstrate the search results: Manaus, Recife, Cuiabá, Brasília, São Paulo and Porto Alegre. In La Niña years there is a decrease in air temperature in almost all regions of Brazil. The impact of ENSO in the country is more observed in winter and spring.

Os resultados da pesquisa mostram a relação quase que direta entre ENOS (El Niño-Oscilação Sul) e as temperaturas máximas e mínimas mensais no Brasil. Foram escolhidas algumas localidades para demonstrar os resultados da pesquisa: Manaus, Recife, Cuiabá, Brasília, São Paulo e Porto Alegre. Os eventos de El Niño contribuem para o aumento das temperaturas máximas e mínimas enquanto o inverso ocorre em eventos de La Niña, exceto para a região Amazônica. Em anos de La Niña ocorrem diminuição das temperaturas do ar em quase todas as regiões do Brasil. O impacto do fenômeno ENOS no país se faz mais presente nos meses de inverno e primavera.UFVJM2012-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos Paresapplication/pdfhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/610.5281/zenodo.3968883Revista Espinhaço ; Revista Espinhaço #12317-0611reponame:Revista Espinhaçoinstname:Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)instacron:UFVJMporhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/6/5Copyright (c) 2022 Revista Espinhaço https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessGuimarães, Daniel P.
