Recent Changes in Temperature and Precipitation Extremes in an Ecological Reserve in Federal District, Brazil

The main objective of this study is to provide information on trends, in local scale, using records of daily temperature and precipitation of a single weather station in an ecological reserve of the savanna biome in Federal District/Brazil, analyzing different extreme climatic indices. The extreme temperature indices have identified that the days are getting warmer and the nights are cooler at local scale. Thus, the local diurnal temperature range is increasing. The results also evidence that the number of days with heavy precipitation is decreasing, but the precipitation indices presented high variability and suggest the importance of further studies related to changes in land use and urbanization. The locally obtained temperature results point to changes in South America.
