Abstract

Rainfall normals based upon the data of two periods, viz. 1901-50 and 1951-80, are compared. The study shows that in eastern India there has been a definite decrease in mean annual rainfall. Also, in the latest normals the number of observatory stations recording 50 cm (500 mm) of rainfall in a day is far less. A generalized chart has been prepared showing the ratios of the highest one-day rainfalls to mean annual rainfall for the observatory stations. The highest ratio in the latest normals was found to be 116 of mean annual rainfall while in the case of the earlier normals this ratio was as high as 130. The zone of occurrence of ratios with 100 and above remains unchanged in both the normal maps for the extreme western parts of the country.
