  • Routine hourly observations of ionospheric characteristics have been taken at Wuchang since August 20. 1946. In this paper a general analysis of the data obtained from September 1946 through December 1947 is attempted. The diurnal and seasonal variations of ionization density and virtual height for all regular layers (E, F-l, F-2) are plotted in diagrams and briefly explained. Deviations from the normally recognized characteristics are discussed in more detail.Besides the normal characteristics, some special phenomena such as the occurrence of E2 near Sunrise and two major ionospheric storms are briefly described. Comparatively detailed study is made on the sporadic E ionization, with the conclusion that its percentage time of occurrence before mid-night is more than that after mid-night and that it is more prevalent in autumn than in any other season. Abnormally high E3 ionization was observed on October 10, 1946 when the Giacobini-Zinner comet was nearest the Earth. These facts indicate that metenrs are probably important agents in producing sporadic E jouization.
