Estimation of Natural Variability and Detection of Anthropogenic Signal in Summertime Precipitation over South America

<table>Time evolution of the rainfall EOF1 for the preindustrial run (green), the 20th century run (blue), and the A1B scenario (magenta). The time series are constructed projecting the precipitation anomalies, calculated with respect to the climatology of the 20th century, onto the spatial pattern of EOF1. </table>
