Trends in daily precipitation in highlands region of Santa Catarina, southern Brazil

Abstract: This study evaluates the occurrence of trends in time series of precipitation in the highlands region of Santa Catarina, Southern Brazil. Daily precipitation data of three weather stations at Lages, São Joaquim and Campos Novos were used to evaluate rainfall trends. The trends were analyzed through the Seasonal Mann Kendall test, to include occurrence of maximum annual 1-day precipitation (RX1), maximum annual consecutive 2-day precipitation (RX2) and maximum annual consecutive 3-day precipitation (RX3) and ev… Show more

“…(1) the first scenario generates samples of the Exponential distribution with the estimated parameters, and 2the second scenario generates samples of the GPD with the estimated parameters. Each scenario [(k = (1), (2)] is repeated 10000 times, according to the Monte Carlo simulation procedure, following the steps described below:…”

“…Furthermore, the series of monthly highs are independent, with 1% level of significance. We should highlight that we have used these tests to verify the assumptions of the Extreme Value Theory models, but that they could be used for other interests, such as [2,29,34] in the trend analysis of hydro-climatic series. In addition, the Kolmogorov-Smirnov test states that both distributions were fitted in all months and the QQ plots corroborate the results (Fig.…”

“…Na América do Sul, observações indicam que nas últimas décadas houve um aumento da precipitação na região norte e redução na região sul (Lee et al 2011). No Brasil, as pesquisas mostram que tem ocorrido nas últimas quatro décadas um aumento de chuvas na região sul e sudeste, enquanto que o centro-norte do país tem apresentado tendências de redução da precipitação (Ávila et al 2016;Salviano et al 2016;Zandonadi et al 2016;Sá et al 2018).…”
