The Weather of 1911 and the Ultra-violet Radiations of the Sun

Abstract

IN connection with an extremely interesting discussion recently carried on in the correspondence columns of NATURE I ventured to direct attention (NATURE, December 14, 1911) to the unusual diminution of the ultra-violet radiation from the sun as a possible cause of the abnormal weather of the summer of 1911. My intention was less to explain the particular phenomenon of this summer than to direct the attention of meteorologists to a new point of view. In so far I succeeded, for a series of letters in NATURE devoted attention to this point. The fullest treatment was contained in a letter from Mr. L. G. Schultz in the issue of March 14.
