Rainfall Statistics: An Interactive Approach to Analysing Rainfall Records for Agricultural Purposes

Abstract

SUMMARY: A continuous daily rainfall record provides much information for agriculturalists but initial questions are imprecise and are modified in the light of experience. In order to match this uncertainty the program ‘Rainfall Statistics’ is designed as a simple interactive procedure for studying quantity probabilities, dry spell frequencies and a simple soil-moisture budget. The program has various functions depending upon user requirements. Use of the program is illustrated with rainfall records from northern Thailand.
