Summary
On the basis of all available record, a series of summer monsoon rainfall of India as a whole has been obtained for the period 1841 to 1977. Years of bad monsoon over the country have been identified. It has been shown that the occurrences of bad monsoon years are random events in the time continuum and that the number of bad monson years in a five-year period is distributed according to the Poisson probability law. A bad monsoon year dislocates the country's economy. To avoid this the country may provide adequate funds keeping in view the probability of getting bad monsson year(s) in a five-year period.
Zusammenfassung
Aufgrund aller verfügbaren Aufzeichnungen wurde eine Reihe der Sommermonsunregen über ganz Indien für die Periode 1841 bis 1977 zusammengestellt; daraus wurden die schlechten Monsunjahre festgestellt. Es wurde gezeigt, daß das Vorkommen schlechter Monsunjahre zufällige Ereignisse im Zeitkontinuum sind und daß die Anzahl von in füntjährigen Perioden vorkommenden schlechten Monsunjahren entsprechend dem Poissonschen Wahrscheinlichkeitsgesetz verteilt ist.
