Abstract

                                An analysis was taken up to find out the validity of forecasting annual rainfall by using Tamil almanac information and 90 years (1909-1999) historical rainfall data of Coimbatore. The results revealed that the annual rainfall of a particular Tamil year in a cycle was not the same for the corresponding Tamil year in the fourth- coming cycle and one can expect an opposite event. There was no correlation between occurrence of rainfall at specific dates and total annual rainfall. Between dates of rainfall within a Tamil year had correlation.

Key words : Rainfall forecasting, Tamil almanac.
