Para este propósito, se utilizaron series anuales de totales de precipitación con la mayor cantidad de datos posibles, provenientes de puntos de medición en el departamento de Cochabamba. El análisis realizado mostró que la precipitación está disminuyendo, principalmente en el sur del departamento, en las provincias de Mizque, Campero y el sur de Carrasco. Este fenómeno no fue detectado en la vertiente norte de la cordillera del Tunari, donde, por el contrario, se presentó un incremento en la cantidad de lluvia precipitada. A su vez, se detectó que la precipitación del año hidrológico 2022-2023 presenta un déficit de entre el 31% y el 56% de la precipitación anual de largo período. Con el propósito de incorporar en el estudio los efectos del El Niño y La Niña, el análisis de la variabilidad, la oscilación y la tendencia en los ciclos de estos fenómenos, y su teleconexión con la precipitación, revela que los eventos de El Niño podrían acentuarse en el futuro, lo cual incide negativamente en la disponibilidad de agua proveniente de la lluvia en nuestra región. Además, nos encontramos en la meseta de un ciclo de sequía que podría durar algunos años más. Por lo tanto, es indispensable continuar con el análisis de los datos meteorológicos para apoyar la toma de decisiones anticipadas, con el fin de reducir los impactos del déficit de precipitación que pueda suscitarse en el futuro.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT During the hydrological year from August 2022 to July 2023, a notable water shortage was observed in the department of Cochabamba and in several regions of the country, which prompted the need to assess the behavior of precipitation and its trend. For this purpose, annual series of total precipitation with the most data possible were used, sourced from measurement points in the department of Cochabamba. The analysis revealed that precipitation is decreasing, primarily in the southern part of the department, in the provinces of Mizque, Campero, and the southern part of Carrasco. This phenomenon was not observed in the northern slope of the Tunari mountain range, where, on the contrary, an increase in the amount of rainfall was recorded. Additionally, it was found that the precipitation for the 2022-2023 hydrological year presents a deficit ranging from 31% to 56% of the long-term annual precipitation. To incorporate the effects of El Niño and La Niña into the study, the analysis of variability, oscillation, and trends in these cycles and their teleconnection with precipitation reveals that El Niño events may become more pronounced in the future, which negatively impacts the availability of rainwater in our region. Furthermore, we are currently in the midst of a drought cycle that could last for several more years. Therefore, it is essential to continue analyzing meteorological data to support decision-making in advance, in order to reduce the impacts of potential precipitation deficits in the future.]]></p></abstract>
