Indian Rainfall and Sun-spots

Abstract

SINCE my last communication to you on the above subject I have had some correspondence with Mr. Hill, the meteorological reporter to the North-West Provinces, in the course of which he has given me a more definite account of the results of his investigations. The outcome of our joint researches may be broadly stated as follows:—In years of maximum sun-spot the summer rainfall is above and the winter rainfall below the average, while in years of minimum sun-spot the reverse conditions hold, viz., the summer rainfall is below and the winter rainfall above the average.
