          Abstract

          El conocimiento de El Niño-Oscilación del Sur (ENOS) aún es parcial; las variaciones del clima colombiano y de eventos ENOS dificultan su entendimiento y la predicción de sus impactos. Esta investigación utilizó el Climate Explorer para establecer relaciones lineales entre la precipitación y la temperatura media del aire (anual y trimestral) de Colombia con variables asociadas a ENOS, entre 1975-2000. Se concluye que al centro, norte y occidente del país, El Niño (fase cálida) trae disminución de lluvias e incrementa la temperatura, lo contrario sucede durante La Niña. Mayores correlaciones significativas se obtuvieron con períodos trimestrales (principalmente en DEF) y rezagos alrededor de cero; éstas decaen en el trimestre MAM de las variables climatológicas; entre la precipitación y el índice IMENSO se obtuvieron mayores coeficientes en DEF (r=-0.44). Existe mayor incidencia de ENOS sobre la temperatura del país.

          The knowledge of the phenomenon El Niño Southern Oscillation (ENSO) still is partial, the variations in the Colombian climate and the ENSO events make difficult its understanding and the prediction of its impacts. This research used the Climate Explorer, to establish linear relations between the precipitation and the average temperature of the air (annual and quarterly) with associated variables to ENSO, between 1975 and 2000. It is concluded that in the center, north and west of the country, El Niño (warm phase) brings rain diminution and increases the temperature, the opposite happens during La Niña. Greater significant correlations obtained with quarterly periods (mainly in DJF) and lags around zero; which decay in trimester MAM of the climatological variables; between the precipitation and index IMENSO greater coefficients in DJF were obtained (r=-0.44). Greater incidence of ENSO exists on the temperature of the country.
