A STUDY OF THE MORPHOLOGY OF GEOMAGNETIC STORMS
Abstract
The verage morphology of magnetic storms with sudden commencement was studied with 346 magn tic storms that occurred in the years 1902 to 1945. Magnetic recor from 26 observatories were used. The 346 storms were classed into three intensity groups of great, moderate and weak storms, and their morphology was investig ted s par t ly S OR VARI TION WAS ANALYZED INTO WO PARTS, Dst and DS. DS was naly ed harmonically, and its changes with storm time were studied in great detail. The author's present views on stor sudden commencements and on the b ormal nature of t e storm variations at the geomagnetic equator are briefly reviewed. (Author)
