A team of scientists led by the National Center for Atmospheric Research is predicting that the sunspot cycle that started this fall could be one of the strongest since record-keeping began.In a new a...
The Influence of Solar Activity on the Rainfall over India: Cycle-to-Cycle Variations
Solar activity Indian rainfall galactic cosmic rays volcanic or interstellar dust
