Trend of Air Temperature in the State of Paraná, Brazil (Tendência Da Temperatura Do Ar No Estado Do Paraná, Brasil)

Abstract: Considering the importance of climatologic series and the local temperature variability analyses, this study aimed to evaluate the trend of maximum and minimum air temperature in the State of Paraná, Brazil. It were used daily data for the period 1980 to 2009 of 28 locations. The trend magnitude was obtained through linear regression and statistical significance using the Mann-Kendall non-parametric test. The spatial distribution of changes found was represented in geo-referenced maps elaborated through the AR… Show more

“…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).…”
