✦ Synopsis

To study the persistence structure causing interannual variability in monsoon rainfall, stochastic modelling of monsoon rainfall data at 50 different stations across India has been attempted. For this, correlograms and partial correlogram wherever necessary, have been developed from 41 years of data at each station. Due to the resulting non-existence of persistence structure in the data, statistical modelling of these data have been carried out instead for quantitative estimation of monsoon rainfall at specified recurrence intervals. To overcome the difficulties in choice of a statistical distribution, it has been proposed to use the method of power transformation, the results of which have been used for verification with the observed rainfall at all stations. Using the observed information, maps have been developed which can be used for quantitative estimation of monsoon rainfall at ungauged locations.
