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

Earth and Space Science, Volume 6, Issue 6, Page 914-930, June 2019., 2019
Abstract 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 motions (SLPMs) have substantial impact on the runoff of the world's large rivers. We estimate that SLPMs can produce a change of the world's large
