Summary

In a previous paper, maps were provided of the extreme monsoonal rainfall deficits likely to occur somewhere within individual Standard Meteorological Sub-Divisions in India. The present paper extends this study to similar evaluations for areas of radius 150 km around each of the 306 stations used in the previous study. Maps are presented of percentage rainfall deficits (or percentage of average values) with return periods of 2, 5, 10 and 50 years, and of the spatial pattern of return periods for deficits of 40%, 50%, 60% and 70% below the average. In addition, there are graphs for 25 stations displaying the relationships between deficit intensity and return period.

Zusammenfassung

In einer vorhergehenden Arbeit wurden Karten über extreme Monsonregendefizite vorgelegt, wie sie wahrscheinlich innerhalb der einzelnen meteorologischen Untereinheiten Indiens vorkommen. Diese Arbeit präzisiert diese Studien auf Gebiete im Umkreis von 150 km jeder der 306 schon früher verwendeten Meßstationen. Hierbei werden Karten vorgelegt, die sowohl Prozentsätze der Regendefizite (bzw. der Durchschnittswerte) für Wiederholungszeiten von 2, 5, 10 und 50 Jahren als auch räumliche Muster der Wiederholungszeiten für Defizite von 40, 50, 60 und 70% unter dem Durchschnittswert angeben. Dem sind Grafiken von 25 Stationen beigefügt, die die Zusammenhänge von Defizitintensität und Wiederholungszeit zeigen.
