Comparison of hydroclimatic data in the department of Cesar, Colombia in the months of February for 1990 and 2022
This study analyzes hydroclimatic changes in the Cesar department, Colombia, during February for the years 1990 and 2022, using climatic data from the climateR library (v0.3.2) in RStudio. The analysis focused on key variables such as accumulated precipitation (PPT), actual evapotranspiration (AET), climatic water deficit (DEF), reference evapotranspiration (ETP), and the Palmer Drought Severity Index (PDSI). February was chosen due to its historically dry nature, with an average precipitation of 31.51 mm. The results show a 48% decrease in average accumulated precipitation, accompanied by an 8.9% increase in reference evapotranspiration and a 26% reduction in actual evapotranspiration. The PDSI evidenced a shift from positive values (+1.659 in 1990) to negative values (-1.877 in 2022), indicating an increase in drought severity. Additionally, DEF increased, reflecting greater water stress. In conclusion, there has been a significant deterioration in water conditions, exacerbating the climate vulnerability of Cesar.
