  Los excesos de lluvia y las heladas meteorológicas son fenómenos adversos en la agricultura, que ocasionan daños irreparables en la fisiología de las plantas, reduciendo la productividad de biomasa de éstas. Con el objetivo de establecer aquellas áreas de mayor amenaza ante tales fenómenos, se realizó el análisis para un periodo de 30 años, empleando 37 series climáticas diarias de precipitación y 23 de temperatura mínima, localizadas a lo largo del Altiplano Cundiboyacense, en la región Andina central de Colombia.

  Excess rainfall and meteorological frosts are adverse phenomena in agriculture, which cause irreparable damage to the physiology of plants, reducing the biomass productivity of plants. In order to establish those areas of greatest threat to such phenomena, the analysis was carried out for a period of 30 years, using 37 daily climatic series of precipitation and 23 of minimum temperature, located along the Cundiboyacense high plateau, in the central Andean region of Colombia. For excess rainfall, we used the Gumbel distribution curve that models the series of maximum rains added to ten days for each month, with the aim of calculating the probable value in return periods to 2, 5, 10, 20 and 50 years. For frosts, climatic series of minimum daily temperature were analyzed, calculating the relative frequency of records less than 0 °C an indicative value of meteorological frost. As a result, maximum values of extreme rainfall are expected in the south-western margin and in the north. On the other hand, the highest probability of occurrence of frost is expected in the center-west and northeast, with values up to 0.71
