Análisis exploratorio de la variabilidad en baja frecuencia de la precipitación anual y estacional en La Plata Observatorio
Abstract
El comportamiento de la precipitación resulta relevante a la economı́a regional y la dinámica urbana en La Plata y alrededores. En este trabajo se evalúa la variabilidad de la precipitación anual y estacional mediante distintas técnicas, utilizando datos de la estación meteorológica La Plata Observatorio, considerando un perı́odo extenso de tiempo (1909-2013). Los resultados permitieron encontrar puntos de quiebres que dan cuenta de cambios en los regı́menes de precipitación, tanto en la serie anual como en la serie de valores estivales, consistentes con lo documentado en la bibliografı́a. Asimismo, se hallaron periodicidades dominantes entre 4 y 8 años coherentes con la incidencia de fenómenos de gran escala como El Niño Oscilación del Sur.
