          Abstract

          Thirty years (1951-1980) of mean monthly thunderstorms days (TS) and rainfall (RF) amounts for 260 Indian observatories spread uniformly over the country were used to obtain their monthly, seasonal and zonal percentage of occurrence from all India totals. The study has revealed that there is a time lag of one month in the occurrence of peak activity of TS and RF. Seasonal analysis of these two parameters suggest that rainfall yield associated with postmonsoon season TS seems to be higher than the premonsoon season. Six zone analysis of TS and RF has suggested that there exists a wide range of variation in both parameters month after month in that zones, but the 30 year mean percentage of occurrence seems to be more or less equal in magnitude in each zone.

          Se utilizaron las medias mensuales de días de tormenta (TS) y cantidad de lluvia (RF) correspondientes a treinta años (1951-1980), obtenidas de 260 observatorios distribuidos de manera uniforme en el país, para obtener los porcentajes de ocurrencia mensuales, estacionales y zonales a partir de los totales de la India. Los resultados indican que hay un lapso de tiempo de un mes entre la presentación de los picos de actividad de TS y RF. El análisis estacional de estos dos parámetros sugiere que la precipitación asociada con la temporada de TS postmonzón parece ser mayor que la de la temporada premonzón. El análisis de TS y RF en seis zonas indica que hay un gran rango de variación en los dos parámetros mes tras mes en estas zonas, pero que la media de treinta años del porcentaje de ocurrencia es más o menos de la misma magnitud en cada zona.
