| description | The investigation analyzed the spatial and temporal scenarios of extreme precipitation events in Bogotá, Colombia, based on the development of climate end indexes endorsed by the Intergovernmental Panel on Climate Change (IPCC) and their capacity to predict climate trends. Data of daily frequency and records of thirty years of 23 meteorological stations distributed widely in the city were worked, in order to provide the greatest amount of spatial information. The quality and absence of data were controlled. The climatological profile revealed two monthly rainfall regimes in the study area with values of up to 87.2 mm / day of precipitation, in addition two broad areas of precipitation convergence were found. The indexes showed a positive regional trend except in the south of the city where negative trends were presented, which projected notable changes in the intensity, duration and frequency of extreme events, in the same way the geostatistical analysis detailed the eastern area with a wide nuance in hydrological dynamics, appropriate to be explored in future research. Ultimately, this research is aimed at expanding and disseminating key information in the planning and planning of the territory, as well as in the prevention and management of risk in the face of extreme weather scenarios such as landslides, floods or droughts in cities located by above 2000 m.a.s.l. and in this way help decision makers, researchers, professors and university students to use an internationally approved methodology that unifies criteria for the collation of climate information. |

La investigación analizó los escenarios espaciales y temporales de eventos extremos de precipitación en Bogotá, Colombia, a partir del desarrollo de los índices de extremos climáticos avalados por el Panel Intergubernamental del Cambio Climático (IPCC) y por su capacidad de predicción de tendencias climáticas. Se trabajaron datos de frecuencia diaria y registros de treinta años de 23 estaciones meteorológicas distribuidas ampliamente en la ciudad, con el fin de brindar la mayor cantidad de información espacial. Se controló la calidad y ausencia de datos. El perfil climatológico reveló dos regímenes pluviométricos mensuales en el área de estudio con valores de hasta 87.2 mm/día de precipitación, además se encontraron dos amplias zonas de convergencia de precipitación. Los índices evidenciaron una tendencia positiva regional salvo en el sur de la ciudad que se presentaron tendencias negativas, lo que proyectó notables cambios en la intensidad, duración y frecuencia de eventos extremos, de igual manera el análisis geoestadístico detalló la zona oriental con un amplio matiz en la dinámica hidrológica, apropiada para explorarse en futuras investigaciones. En última instancia, esta investigación se orienta en ampliar y divulgar información clave en la planeación y ordenación del territorio, así como también en la prevención y gestión del riesgo frente a escenarios de extremos climáticos como deslizamientos de tierra, inundaciones o sequias en ciudades situadas por encima de los 2000 m.s.n.m. y de esta manera ayudar a tomadores de decisiones, investigadores, profesores y estudiantes universitarios en emplear una metodología aprobada internacionalmente que unifica criterios para el cotejo de información climática.
