Abstract
BY aid of R. Wolf's series,1 I have been endeavouring, if possible, to trace the effect of the different state of the sun's surface, as shown by the extent of its spots, on our climate. I distributed the annual rainfall, registered here 1833-1863, into ten classes, according to the corresponding values of “the relative numbers” r, as exhibited in Table I. These relative numbers have been determined by Prof. Wolf from a discussion of the registered number of spots and groups of spots on the sun, and are supposed to be proportional to the area covered by spots on the sun's surface. The mean rainfall M, the average of the thirty-one years, is 37.254 inches, o is the rainfall registered during a certain year —. I tried to reduce the difference o — M (Table II.) by applying to M a constant correction, 10 x, and at the same time a correction r y proportional to the respective relative number. The equations of condition of the form—
