The results of an analysis of climate variability associated to the ENSO cycle for the Bogotá Highlands are presented. For this analysis we used data of sea surface temperature (SST) anomalies from the EN1+2, 3, and 3+4 sectors of the tropical Pacific, regional monthly mean air temperature and monthly precipitation. An inverse relationship between SST anomalies and precipitation in the Bogotá Highlands was identified: warm conditions (positive SST anomalies related to El Niño) reduce regional precipitation, while cold conditions (negative anomalies associated to La Niña) increase it. The regio... Mehr ...
