The hydroclimatology of Gorgona Island : seasonal and ENSO-related Patternsa

ABSTRACT: Most small watersheds in the Tropical Eastern Pacific remain ungauged, and discharge analyses using gauge and simulated data have been published only for a few large rivers. I analyzed a 20-yr record of rainfall and stream discharge from Gorgona Island, a natural national park located 30 k...

description ABSTRACT: Most small watersheds in the Tropical Eastern Pacific remain ungauged, and discharge analyses using gauge and simulated data have been published only for a few large rivers. I analyzed a 20-yr record of rainfall and stream discharge from Gorgona Island, a natural national park located 30 km offshore in the Pacific Ocean of Colombia to explore intra- and inter-annual patterns and drivers. Gorgona Island receives > 6.600 mm of annual rainfall thus feeding numerous permanent streams. Inter Tropical Convergence Zone-driven seasonal rainfall patterns (unimodal) were consistent regardless of interannual variability. However, a large yearly variation was observed between May and August. Monthly and annual rainfall in Gorgona Island was greater than at a neighboring continental-coastal area, suggesting the occurrence of orographic and convective rain. El Niño Southern Oscillation slightly influenced interannual variation in rainfall, but it strongly influenced stream discharge. The importance of the Chocó Jet Current and Meso-Scale Stationary Systems is discussed.

Se analizó un registro de 20 años de precipitación y caudales de la Isla Gorgona, un parque nacional natural ubicado a 30 km de la costa Pacífica colombiana para identificar patrones de variabilidad intra- e inter-anual. La Isla recibe > 6.600 mm de lluvia anualmente que alimentan numerosas quebradas permanentes. El patrón monomodal de precipitación es consistente a pesar de la variación interanual y determinado por la migración latitudinal de la Zona de Convergencia Intertropical. Sin embargo, una mayor variación entre años fue observada en el periodo mayo-agosto. Las lluvias mensuales y anuales fueron mayores que las de áreas costeras continentales vecinas, lo que sugiere la ocurrencia de lluvia orográfica y convectiva. El Niño - Oscilación Sureña influenció levemente la dinámica de la lluvia, pero fuertemente la del caudal. Se discute la importancia de otros sistemas atmosféricos como la Corriente de Chorro del Chocó y Sistemas Estacionarios de Meso-Escala.COL010175911application/pdfengUniversidad de Antioquia, Facultad de Ciencias Exactas y Naturales, Instituto de BiologíaMedellín, Colombiahttps://creativecommons.org/licenses/by-nc-sa/4.0/http://creativecommons.org/licenses/by-nc-sa/2.5/co/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2The hydroclimatology of Gorgona Island : seasonal and ENSO-related PatternsaHidroclimatología de la isla Gorgona : patrones estacionales y relacionados con el ENSOArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionEstaciones del AñoSeasonsFenómeno de la NiñaLa Niña PhenomenonFenómeno de El NiñoEl Niño PhenomenonPrecipitación pluvialGorgona Island (Cauca)Isla Gorgona (Colombi)Gorgona island (Colombia)HidroclimatologíaHydroclimatologyCaudal de la corriente de aguaStream flowEstacionalidadSeasonalityRecursos hidrológicosClimatologíahttp://aims.fao.org/aos/agrovoc/c_3721http://aims.fao.org/aos/agrovoc/c_1cb3b243http://aims.fao.org/aos/agrovoc/c_34117Actual.
