Abstract
Based on the interaction between earth and moon in relation to sun, each month is governed by both new moon and full moon. In between these two there are fourteen thithies (moon phases) covering the 14 days interval. A study was undertaken to find out the association between rainfall and the different thithies. Daily rainfall data were collected from Department of Agricultural Meteorology, Tamil Nadi Agricultural University, Coimbatore, India for the period from 1991-2000. Results revealed that the first eight thithies succeeding new moon, and eight thithies preceding the new moon did relate to annual rainfall events. Higher rainfall occurred normally during the eight thithies preceding the new moon as compared to thithies succeeding the new moon. Almost similar results could be noticed for both south west and north east monsoon seasons. Analysis also indicated that towards full moon phase, the thithi Shashti (sixth phase) is associated with high rainfall while such effect was noticed at Ekadasi (eleventh phase) thithi towards new moon. High intensity events occurred frequently during new moon phase as compared to full moon phase.
