Abstract

Quantitative precipitation forecasting (QPF) of daily rainfall of Thiruvananthapuram and Madras  for June-September and October-December respectively for the year 1992 has been attempted. A mathematical model of QPF based on the concept of conservation of specific humidity and with upper air data of a network of stations as the data input has been employed. Nearly 66% and 72% correct forecasts were realised respectively for the two stations. Scope for further refinement has been briefly discussed.
