Figure 6
Change in annual total rainfall and annual frequency of rainy days in the Brazilian Cerrado between 1960 and 2021. (a, b) Mann–Kendall test over 1960–2021 for annual total rainfall (mm) and frequency of rainy days, respectively. The blue, red, and gray colors represent the areas with a significant increasing trend (p < 0.05), significant decreasing trend (p < 0.05), and non-significant trend, respectively. (c) Regional changes detected by ERA5 reanalysis for annual total rainfall (mm/day). The dotted areas demonstrated a significant difference (p < 0.05) between the climate normals 2021–1991 and 1960–1990. (d and e) Local changes in annual total rainfall and annual frequency of rainy days by comparing the climate normal 1991–2021 to the climate normal 1960–1990, respectively. Maps showing local scale trends were generated using ArcGIS (https://www.arcgis.com). The ERA5 reanalysis map were generated using GrADS-Grid Analysis and Display System (http://opengrads.org).
