The relationship between the extreme draught events on northern Colombia and large scale atmospheric circulation is evaluated. It is characterized by the Tropical North Atlantic (TNA) and El Niño 3,4 indexes. The topography of the Sierra Nevada de Santa Marta range, in the center of the littoral, determines synoptic scale variations in precipitation records. Standard Precipitation Index (SPI) and time series on frequency, intensity, extent and magnitude of extreme draught events were calculated. Significant relationships between extremes of drought and NIÑO 3.4 index detected, increased slightly towards the Northern Caribbean Coast, during the period August-October (ASO), while the TNA index relations are detected during June-August (JJA). This study provides a comprehensive view of the... mechanisms involved in the generation of extreme drought events modulated by the influence of atmospheric circulation phenomena in the Atlantic and Pacific Oceans.
