                         studies that address the issue of possible short-term forecasting 
                         of EPB. We report the observations of the Equatorial 
                         Quasi-Periodic-Electric field Disturbances (QP-EDs) of the 
                         Field-aligned Irregularities (FAI) in the E region before the EPB 
                         occurrence in the F region. They are observed from 30 MHz coherent 
                         scatter radar during the SpreadFEx campaign 2005 carried out in 
                         Brasil. The presently reported QP-EDs at the equatorial E region 
                         below an altitude of 110 km are undescribed so far. Though QP-EDs 
                         characteristics vary on a day-to-day basis, consistent features 
                         are their intensification before the EPB, and their simultaneous 
                         occurrence with EPBs. This study highlights the monitoring of 
                         QP-EDs in the short-term forecasting of EPBs and further reveals 
                         the robust energetics of vertical coupling between E and F 
                         regions.",
