A note on the accuracy of the auroral electrojet indices

Journal of Geophysical Research Atmospheres (1983)

S.‐I. Akasofu B.‐H. Ahn Y. Kamide J. H. Allen

The accuracy of the present AE(12) index is evaluated by using magnetometer data from the six IMS meridian chains and other high‐latitude stations. It is shown that the accuracy of AE(12) becomes progressively worse for lower values. There are at least a few causes for this inaccuracy, and three of them are identified. Although it is not possible to provide a single critical value, one should be cautious about the accuracy of the absolute value of AE(12) less than ∼250 nT. In particular, since 70% of AE(12) values are less than 250 nT, one must be cautious in correlative use of the AE(12) index with solar wind parameters.

Pseudobreakups During January 10, 1997

The January 10, 1997 interplanetary pressure pulse (observed at 0053 UT at Wind) caused a dayside aurora, as seen in Polar Ultraviolet Imager (UVI) data, that propagates tailward and to lower L.

Global Ionospheric Convection During Substorm Expansion

G. Lu A. D. Richmond Y. Kamide D. Lummerzheim M. Brittnacher

The large-scale ionospheric convection patterns derived from the Assimilative Mapping of Ionospheric Electrodynamics (AMIE) procedure are used to examine the relationship between global convection and the substorm expansion. It is found that, after the onset of the substorm expansion when the AL index begins to decrease sharply, an isolated convection cell evolves near midnight. As the substorm progresses, this cell expands, gradually merging with the pre-existing dusk-side convection cell. When the pre-substorm expansion convection pattern is subtracted, the residual patterns show clearly a 2-cell convection configuration which first appears in the local midnight sector after the onset of the expansion phase and gradually intensifies in spatial size as well as in magnitude during the expansion phase. Such a configuration implies that the substorm-related ionospheric convection is mainly controlled by a magnetospheric process in the tail.
