In SPIChanges: Improves the Interpretation of the Standardized Precipitation Index Under Changing Climate Conditions

#' Changes in Drought Events in Brazil (1980-2024)
#'
#' This dataset provides the changes (in percentage) in Moderate to Extreme, Severe to Extreme, and Extreme Drought events across Brazil
#' for the four seasons (Summer, Autumn, Winter, and Spring) over the period 1980–2024.
#' The data were generated using the `SPIChanges()` function applied to rainfall data from NOAA PSL.
