Abstract
THE American Meteorological Journal for September contains the conclusion of “Objections to Faye's Theory of Cyclones,” by W. C. Moore. Only a few of the more essential characteristics of cyclonic storms have been considered, but from these the author concludes that it is evident that the generally accepted theory of convectional motion gives a more satisfactory explanation of the various phenomena than the theory advanced by M. Faye.—“Changes of Plane of the Mississippi River,” by Prof. T. Russell. The author analyses a report by Colonel C. R. Suter, of the Mississippi River Commission relating to the improvement of the river and methods of preventing overflow.—“Thunderstorms in New England during the Year 1887,” by R. de C. Ward. The difficulty of predicting thunderstorms is shown by the fact that in New England in 1887 the majority of storms occurred in the southeastern quadrant of cyclones, while in the previous year the majority occurred in the southern or south-western quadrant. Only 40 per cent. of the summer thunderstorms of 1887 occurred in the southern part of cyclonic storms, while in the previous year the number was 70 per cent.—“Weather Forecasting at the Signal Office, June 30, 1891,” by Prof. H. A. Hazen. At this date the weather service was transferred to the Agricultural Department, and the author has given the results of his experience by laying down certain fundamental rules which would be of service to a beginner in the work, as it has sometimes been suggested that it would be almost impossible for a forecaster to impart his knowledge to another.—“The Effect of Topography upon Thunderstorms,” by R. S. Tarr. The author's observations have led him to believe that topography has a decided effect upon the path of thunderstorms when they are beginning. When, however, the storm has assumed more than local proportions, topography has in all probability very little effect upon its motion.
