| Abstract: | An attempt is made to examine the association, if any, between the rainfall in Tamil Nadu and sunspot activity and if so, whether similar periodicities are also present in the sunspot activity. The daily relative sunspot numbers for the period Oct.-Dec, during 1961-70 and the daily sunspot means for the period Oct.-Dec., 1889-1938, as well as the rainfall series for the period Oct.-Nov. during 1961-70 have been analyzed by power spectrum. An anti-phase relation was noticed between the rainfall and the sunspot activity. The 15-day periodicity in the rainfall was significant. The sunspot activity also showed similar periodicities as rainfall. The 30-day periodicity in the sunspot activity was significant. |
