Abstract
American Meteorological Journal, January.—Solar magnetism in meteorology, by Prof. F. H. Bigelow. This article contains some general remarks on the present state of the problems arising out of the relations that have been traced by the author's study of solar magnetism and its influences upon meteorological phenomena. Prof. BigeJow endeavours to show that the usually accepted mode of propagation of energy from the sun to the earth is not the only one that exists, and suggests that another possible mode is due to polarised solar magnetic force, such as surrounds a magnet. The progress of the investigation was made in three distinct stages: (1) the detection of the true period of the sun's rotation; (2) the determination of the intensity of the solar magnetic field from meridian to meri dian of the sun; (3) the discovery of the inversion of the solar magnetism in certain periods. The author expresses the opinion that the convectional hypothesis of cyclones is untenable, and endeavours to show, from an examination of the American meteorological curves for the years 1878–93, that the three systems—the one at the sun, that of the magnetic field in the northern hemisphere, and ihat of the American meteorological field—vary together in block from year to year.—Variations in the character of the seasons, by H. Gawthrop. The division of the year into four seasons is traditional, but when measured as phases of weather, it is not possible to fix these periods within definite limits. The author's investigation leads him to conclude that the primal cause for the variations in the character of the seasons must be traced back through all the effects of diurnal and seasonal insolation, and of the cyclonic storms in the lower atmosphere.
