A link between climate and the motion of the Sun around the barycenter of the solar system has been suggested, mostly on the basis of interannual cycles observed in climatological data from the Northern Hemisphere. This study provides empirical evidence for a connection between this solar motion and discharge of the Paraná River, which has the second largest drainage basin of South America. Solar motion is described here by the absolute value of the time derivative of solar angular momentum… 

Climate changes and solar cycles recorded at the Holocene Paraná Delta, and their impact on human population

TLDR
Results suggest that aside the solar forcing, both short and medium term climate changes controlled delta evolution, suggesting that a slight cooling would turn the highly productive pampas into that unproductive desert and, given the lack of artificial irrigation systems, changing present-day warmhouse into a cooling cycle might be economically catastrophic for the region.

Are southern South American Rivers linked to the solar variability?

This article explores the Sun's influence on the hydrological cycle in southern South America (SSA) at the range of interannual‐to‐multidecadal scales from the early 1900s to 2011. The solar

Detection of Linkage Between Solar and Lunar Cycles and Runoff of the World's Large Rivers

It is an ongoing concern that global hydrological cycle can be likely intensified under context of climate change and anthropogenic actions. Here, our results show that the solar and lunar periodic

Contributions of different time scales to extreme Paraná floods

The present study provides the first complete examination of how different time scales contributed to generate the four largest observed floods of the Paraná River (1905, 1983, 1992 and 1998). This

Possible Origin of Some Periodicities Detected in Solar‐Terrestrial Studies: Earth's Orbital Movements

Periodicities matching planetary cycles have been argued to be detected in key geophysical time series. In general, these periodicities were indirectly attributed to a planetary influence on solar

Analysis of hydroclimatic variability and trends using a novel empirical mode decomposition: Application to the Paraná River Basin

The current understanding of hydroclimatic processes is largely based on time series analysis of observations such as river discharge. Although records of these variables are often nonlinear and

Interannual and Decadal Cycles in River Flows of Southeastern South America

Abstract The time series of annual streamflow of four rivers in southeastern and south-central South America (the Negro, Paraguay, Parana, and Uruguay Rivers) for the period 1911–93 are analyzed.

Low‐frequency response of the upper Paraná basin

The low‐frequency response of the upper Paraná River basin is investigated by means of singular spectral analysis (SSA) applied to precipitation rates and runoff contributions of different

Macroscale water fluxes 3. Effects of land processes on variability of monthly river discharge

A salient characteristic of river discharge is its temporal variability. The time series of flow at a point on a river can be viewed as the superposition of a smooth seasonal cycle and an irregular,

Do Planetary Motions Drive Solar Variability?

We examine the occasionally forwarded hypothesis that solar activity originates by planetary Newtonian attraction on the Sun. We do this by comparing three accelerations working on solar matter at
