摘 要：Several mechanisms including heat transport due to zonal winds, chemical heating and field-line ion drag have been proposed to explain the formation of the Equatorial Thermosphere Anomaly （ETA）, but the real cause of the（ ETA） crests in thermosphere temperature is still a mystery. Various observations of the ionosphere and thermosphere have been used to investigate the variations of equatorial anomalies in both the ETA and EIA, and their interactions. The similarities and differences between the ETA and the EIA can provide important insight to the physical connections of this ion-neutral coupling problem. Meanwhile, the combination of observations and theoretical models allows us to understand the fundamental physical and chemical ion-neutral processes in the equatorial F region. This talk will highlight the recent progress of the formation of the ETA associated with the ion-neutral coupling in the equatorial region.
