Abstract.-The relationship between climatic periods and intensity of 2 upwelling cores located in the Colombian Caribbean from the time analysis of climatic indicators and sea surface temperature (SST) for the period 1990-2009 were analyzed. Four climatic seasons are described for this region with differences and similarities between points located in front of the Guajira Peninsula and Tayrona National Natural Park (PNNT). Spectral analysis of the Ekman transport and differences of SST with the furthest points of the coast estimates, as indicators of the wind stress and the magnitude of the upwelling along the studied period, allow establishing a direct correspondence between the season and the upwelling regime. In the case of surface water off the Guajira Peninsula, there are some oscillations periods that not correspond with wind regime in the area. These oscillations could be influenced by the behavior of the Caribbean Current and/or upwelling cores off Venezuela and/or Trinidad and Tobago. According to the spectral and descriptive analysis applied to ERA Interim data, these reflect well the behavior of the climate in the area, despite their low temporal and spatial resolution.Key words: Precipitation, zonal and meridional wind, Ekman transport, spectral analysis, sea surface temperatureResumen.-Se analizó la relación entre las épocas climáticas y la intensidad de 2 centros de surgencia localizados en el Caribe colombiano a partir del análisis temporal de indicadores climáticos y la temperatura superficial del mar (TSM), para el período 1990-2009. Se describen 4 épocas climáticas en la región con diferencias y similitudes entre puntos localizados frente a la Península de la Guajira y en cercanías del Parque Nacional Natural Tayrona (PNNT). El análisis espectral de las estimaciones de transporte de Ekman y diferencias de TSM, con los puntos más alejados de la costa, como indicadores del esfuerzo del viento y la magnitud de los afloramientos a lo largo del período estudiado, indica una correspondencia directa entre la época climática y el régimen de surgencia. En el caso de las aguas superficiales frente a la Península de la Guajira, se encuentran períodos de oscilación en la TSM distintos al régimen de vientos en la zona. Estas oscilaciones podrían estar influenciadas por el comportamiento de la corriente del Caribe y/o focos de surgencia frente a Venezuela y/o Trinidad y Tobago. De acuerdo al análisis espectral y descriptivo realizado a los datos de ERA Interim, estos reflejan bien el comportamiento del clima en la zona, a pesar de su baja resolución temporal y espacial.Palabras clave: Precipitación, componentes zonal y meridional del viento, transporte de Ekman, temperatura superficial del mar, análisis espectral
