Estimación del régimen de precipitación a partir de la distancia a la cordillera en el noroeste de la Patagonia
Abstract
We estimated mean annual and seasonal precipitation from the distante to the Andes using regression analysis for an area of 16000 km2 in Northwest Chubut (Argentina). Mean annual and seasonal precipitation decreased exponentially eastward of the Andes, whereas the coefficient of variation of annual precipitation increased exponentially. No significant changes in the seasonal distribution of precipitation were detected along this gradient.
