Description:

Ten years of geomagnetic ﬁeld observations by the CHAMP satellite are used for a systematic investigation of the counter equatorial electrojet (CEJ). For the ﬁrst time a comprehensive characterization of CEJ is presented. CEJs occur preferably during early morning, and their occurrence rate is down to 4% atnoon. The CEJ occurrence rate shows a clear annual variation with a peak around July –August and a secondary peak in January. The late summer peak is related to the effect of meteor dust ablation. The CEJ amplitude is closely controlled by magnetic activity, showing a good correlation with the a Pindex. Nonmigrating solar tides are the main reason for longitudinal patterns of occurrence rate.
