LOPEZ VELANDIA, Cristian Camilo. Spatial and Temporal Precipitation Distribution Analysis at Chicú River Basin, Bogotá's High Altitude Savannah, Colombia. Perspectiva Geográfica [online]. 2016, vol.21, n.1, pp.63-90. ISSN 0123-3769.

In this paper the spatio-temporal variability of rainfall in the Chicú river basin was analyzed locally, in order to use it as input to identify potential impacts of climate change and mitigation design and adaptation measures at the municipal or rural level. Historical precipitation information was collected by hydro-meteorological stations present in the region, performing quality analysis and estimation of missing data, in order to generate maps of spatial distribution of rainfall for the region. This region presents an average annual rainfall of 853 mm for the "Providencia" rural weather station (1987-2012). It is influenced by the Inter-confluence of the Tropical Zone. The average monthly precipitation is of bimodal character, generating two rainy periods, the first in the months of April-May (101.9±15.6 mm) and the second in October-November (98.9 ± 19.5 mm), producing significant variations around the spatial distribution of rainfall in the analyzed area during the months studied.

Keywords : Chicú river basing; rainfall spatial and temporal variability; precipitation.
