Tendências de temperaturas mínimas e máximas do ar no Estado de Minas Gerais

Abstract: Resumo -O objetivo deste trabalho foi avaliar tendências das temperaturas mínimas e máximas no Estado de Minas Gerais. Foram avaliados dados de 43 municípios, tendo-se considerado as escalas anual e sazonal -janeiro, abril, julho e outubro, que representam os meses centrais de verão, outono, inverno e primavera, respectivamente. Séries históricas de temperaturas mínimas e máximas do ar diárias, com extensão mínima de 30 anos, foram analisadas com base no teste de Mann-Kendall e no uso de regressão linear simpl… Show more

“…The discussion about potential climate changes has motivated research on the various components of the hydrological cycle, especially those that allow the identification of possible trends or other non-stationarity factors in the records of hydrological variables along the time scale (Ávila et al, 2014;Uliana et al, 2015). According to Joseph et al 2013, the verification of possible nonstationarities in hydrological series is important for the management and handling of hydrographic basins and their available resources.…”

“…O teste de Mann-Kendall é um teste sequencial, robusto e não paramétrico utilizado em muitos estudos que analisam dados de elementos ambientais e suas possíveis tendências (e.g., Luiz et al, 2012;Ávila et al, 2014;Da Silva et al, 2015;Fathian et al, 2016;Salviano et al, 2016; Ely e Dubreuil, 2017). Tal teste é aplicado para verificar se certa série de dados apresenta tendência temporal de modificação estatisticamente significativa.…”

“…For this purpose, the use of linear regression, Mann-Kendall (Mann, 1945;Kendall, 1975) or both tests simultaneous has been used to identify a significant trend in climate data. In Brazil, these tests have been applied to identify significant changes in temperature (Ávila et al, 2014;Ferreira et al, 2015;Neves et al, 2016) and in rainfall (Ely and Dubreuil, 2017;Zilli et al, 2017). In the same way, worldwide studies were conducted to confirm changes in the weather variables mentioned previously (Chen and Zhai, 2017;Shi et al, 2018;Qian et al, 2019).…”
