Estimation of Natural Variability and Detection of Anthropogenic Signal in Summertime Precipitation over South America

Figure 2

Coefficient of 4th-order of the potential associated with the pdf computed using 100-years sliding windows. The larger the value the broader the pdf. The “*” mark is the periods P1 and P2 used in the study, which have different pdfs reflecting different modes of behavior of internal variability in the south American climate.
