  • The characteristics and development of the low-and-mid latitudinal ionospheric storm during the magnetic storm in November, 2004 are studied using GPS observations from 6 stations along 115°E meridian. The results from tomographic reconstruction method show that the ionospheric storm during this magnetic storm mainly exhibits the positive storm phase, and the positive deviations of electron density are not only latitude dependent but also height dependent. The Equatorial Anomaly (EA) crest moves poleward as a result of enhanced energy deposition into the high latitude ionosphere. The electron density and TEC gradually recover to the quiet level in the first recovery phase. These results are in good agreement with previous studies, and the ionospheric effects can be attributed to the storm circulation theory superimposed with the movements of EIA crest.
