STUDY OF RAINFALLS RECORDED AT THE CHERRAPUNJI OBSERVATORY.

Abstract

The maximum rainfalls recorded at the Cherrapunji Observatory raingage in India during various periods within the 57 years from 1903 to 1959 have been studied and the equation of the enveloping line was found. One-day maximum rainfalls for different periods from two to 100 Years have also been worked out and the 100-year value has been found to be 2. 1 times the 2-year value. The daily probable maximum precipitation estimated by the Hershfield technique, is 78 in. A study of annual and monsoon rainfalls did not show any general linear trend but there was a gradual increase in amounts from 1944 to 1954.
