dc.description.abstract | RESUMEN: La cuenca Amazónica ha sido objeto de investigaciones relacionadas con el comportamiento de la precipitación. Se ha evidenciado que la circulación océano-atmósfera es importante en la estacionalidad de la lluvia en este bosque; además se ha evidenciado una influencia significativa de las condiciones locales (flujos de agua y energía). Estudios recientes sugieren que en las últimas décadas se ha presentado un alargamiento de la temporada seca en esta cuenca, debido principalmente a un inicio tardío de la temporada lluviosa. Este trabajo busca relacionar este alargamiento con variables indicadoras de procesos físicos y ecológicos. Nuestros resultados sugieren que la deforestación acelera la frecuencia de aparición de eventos de temporadas secas largas. Palabras clave: Temporada seca, Amazonas, balance de agua y energía, actividad de la vegetación, evapotranspiración, deforestación, balance de energía. | spa |
dc.description.abstract | ABSTRACT: The hydroclimatology of the Amazon basin has been an object of interest due to its climatic, ecological and environmental implications. Many of the research in this region has focused on understanding precipitation behavior and its influence on regional atmospheric dynamics as well as on moisture transport to other regions of South America. Although it has been identified that the ocean-atmosphere circulation plays an important role in the easonality of rainfall in this tropical forest, a significant influence of the local conditions of this region, especially water and energy flows, has also been evidenced in the precipitation behavior. Recent studies show that in the last decades there has been a long dry season for some regions within the Amazon basin, mainly a late onset of the rainy season. Through a combined analysis of observations, reanalysis and databases derived from modeling, this work seeks to relate this lengthening with variables indicators of local and regional physical and ecological processes. For this, we analyzed hydrological variables and variables indicative of vegetation activity in two subregions to the Southern of Amazonas, characterized by the predominance of different types of vegetation cover. Our results suggest that for the subregion further south, with greater anthropogenic intervention and where is found the region called ""Deforestation Arc"", it is evident that dry seasons have appeared with greater frequency in the last decade of the study. Likewise, the results for this subregion indicate that in the long dry seasons the lowest values of the variables indicative of vegetation activity and soil moisture are presented, as well as the higher values of net radiation. These results potentially suggest that the lengthening of the dry season may be associated with a decrease in vegetation activity that induces alterations in the destabilization of the atmosphere, causing delays in the onset dates of the rainy season. Finally, for the subregion with lower anthropogenic intervention, the long dry seasons were less frequent in the last decade. This might suggest that deforestation accelerates the frequency of occurrence of long dry season events. This is importantconsidering that forest loss, combined with lengthening dry season scenarios and external forcing associated with the ocean-atmosphere relationship, could increase the mortality of trees, leading to serious consequences in the availability of local and regional water resources. Keywords: Dry season, Amazonas, water and energy budget, vegetation activity, evapotranspiration, deforestation. | spa |
