Solar forcing of the stream flow of a continental scale South American river
Solar forcing on climate has been reported in several studies although the evidence so far remains inconclusive. Here, we analyze the stream flow of one of the largest rivers in the world, the Paraná in southeastern South America. For the last century, we find a strong correlation with the sunspot n...

Here, we analyze the stream flow of one of the largest rivers in the world, the Paraná in southeastern South America. For the last century, we find a strong correlation with the sunspot number, in multidecadal time scales, and with larger solar activity corresponding to larger stream flow. The correlation coefficient is r=0.78, significant to a 99% level. In shorter time scales we find a strong correlation with El/Niño. These results are a step toward flood prediction, which might have great social and economic impacts. © 2008 The American Physical Society. 2008 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00319007_v101_n16_p_Mauas http://hdl.handle.net/20.500.12110/paper_00319007_v101_n16_p_Mauas |
