摘要

The disturbance time variations of the vertical component (Z) of the geomagnetic field at stations in the Indian chain, following a sudden commencement storm show a spectacularly large decrease at only the electrojet stations, Thiruvananthapuram, Etaiyapuram, Kodaikanal and Annamalainagar. This decrease is not synchronous in time with the decrease of the horizontal (H) field. The peak depression of the Z field occurs about three hours before the time of peak decrease of H, i.e. during the middle of the main phase of the storm, when the ring current is developing at the fastest rate. This first clear description of Dst(Z) at Indian electrojet stations is further confirmation of the sub-surface conducting channel in Palk Strait, where currents are induced by the ionospheric source current, producing large decrease of Z field at ground level. Similar analysis of Dst(Z) at different equatorial stations around the world is recommended to understand the abnormal features of Indian equatorial electrojet.
