Daily weather charts for the sea level and two upper levels for the months of July and August for 30 years (1946-1975) have been categorised for different features of the charts. The coded information is objectively utilised as the basic source for selecting analogues for forecasting rainfall over different parts of the country.


The suits of a forecasting experiment conducted during the monsoon season of 1978 based on the analogues for the prediction of rainfall over the meteorological sub-divisions of the country are discussed. The overall performance of the analogues for forecasting purpose is assessed with respect to operational forecasts and persistence.


The categorised information was also utilised to study the synoptic-climatological aspects of monsoon.
