Abstract

The present research sought to establish the existence of trends in the indices of climate extremes for the department of Caldas. The results were obtained from the analysis of historical series with a record superior to 30 years, 55 in the case of the study of the variables associated to precipitation and 10 in the case of the temperature variable. The analysis was performed using the RClimdex tool, which identified the presence of increasing and decreasing trends, in those stations that presented statistically significant differences (P Values ​​<0.10) in the climatic indicators evaluated. This trend analysis of climatological variables allows to ensure with a level of confidence of 90% that in the department there could be an increase, both in the amount of precipitation and in the duration of the wet periods, but it is concluded that the strengthening of the network of stations in the territory in order to generate analysis of greater coverage, given that the absence of historical series in Magdalena Caldense, Occidente Prospero and Alto Occidente subregions is evident.
