In an attempt to explore the possibility of issuing quantitative daily precipitation forecasts, Some statistical relations between daily rainfall and certain "predictors" - upper wlnds at two levels, vertical stability and humidity distribution and frontal passages - have been derived, based on September to November data for the years 1953-56 inclusive. This study indicates that the value of these "predictors" for the quantitative forecasting of rainfall is limited.
R. H. Clarke (Sat,) studied this question.
