Oceanic influence on southernmost South American precipitation

The potential oceanic influence on southernmost South American precipitation since 1930 is analyzed in this study. The aim is to define oceanic characteristics that can produce wetter or drier conditions over thementioned region on different time scales. Results suggest important precipitation-ocean...
