- 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 distri-bution 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 degrees 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.
