HURTADO MONTOYA, Andrés Felipe  and  MESA SANCHEZ, Óscar José. CLIMATE CHANGE AND SPACE-TIME VARIABILITY OF THE PRECIPITATION IN COLOMBIA. Rev.EIA.Esc.Ing.Antioq [online]. 2015, n.24, pp.131-150. ISSN 1794-1237.

The previous studies about the impact of climate change in Colombian precipitation are reviewed. Arguments in favor of the analysis of observed quantities are presented and limitations of climate models to predict future changes in precipitation are highlighted. The spatial and temporal variability of precipitation, one of the main variables of the water cycle, is studied. For that, it was developed a reanalysis of the precipitation field in Colombia, comprising 384 fields of monthly precipitation in the period 1975-2006 at a spatial resolution of 5 minutes of arc. The research carried out with the available fields was based on the estimation and analysis of Empirical Orthogonal Functions, Principal Components and statistical tests to detect changes or trends over time of monthly precipitation in Colombia. The study advance the understanding of spatial and temporal variability of the water resources in the country, as well as in identifying signs and effects of climate change. A brief discussion about research problems arising from climate change is presented at the end.

Keywords : Precipitation; Reanalysis; Spatial and Temporal Variability; Climate Change.
