| contents | El ciclo anual de la hidrología de Colombia en relación con el ENSO y la NAO Marta María Gil Natalia Quiceno Germán Poveda Multidisciplinarias (Ciencias Sociales) The impact of the El Niño-Southern Oscillation (ENSO) phenomenon ENSO and of the North Atlantic Oscillation (NAO) on the annual cycle of the Colombian hydroclimatology is quantified. Results of the NCEP/NCAR Climatic Reanalysis Project are used to compare the climatology of the annual cycle of diverse variables and to evaluate the behavior during the extreme phases of ENSO. Of particular importance, during El Niño there is a weakening of the low-level westerly jet penetrating from the Pacific Ocean inland Colombia, that constitutes one main circulation mechanism that helps to explain the observed negative hydrological anomalies during El Niño in Colombia. Correlation analysis confirms the strong influence of ENSO and NAO on the annual cycle of rainfall and river discharges anomalies in Colombia, in particular during SON and DJF. 1998 artículo científico 0303-7495 https://www.redalyc.org/articulo.oa?id=12627334 en http://www.redalyc.org/revista.oa?id=126 Bulletin de l'Institut français d'études andines application/pdf Instituto Francés de Estudios Andinos Bulletin de l'Institut français d'études andines (Perú) Num.3 Vol.27 |
