| Abstract: | A critical analysis of Total Column Ozone (TCO) over Dum Dum, West Bengal, India is done during different seasons for the
period of 1997 to 2005. It is confirmed that pre-monsoon rate of change of TCO over Dum Dum is highly correlated with Gangetic
West Bengal, India monsoon rainfall of same year and that of TCO during other seasons are independent of monsoon rainfall
over Gangetic West Bengal. It is also concluded that pre-monsoon rate of change of TCO may play an important role to forecast
monsoon rainfall of a particular year over Gangetic West Bengal. It is also showed that other parameters affecting monsoon
rainfall are insignificant w.r.t. TCO variations. A possible explanation based on chemical kinetics of O3 are also presented. |
