             abstract = "Equatorial plasma bubbles (EPBs), or large-scale plasma depleted 
                         regions, are one of the subjects of great interest in space 
                         weather research since such phenomena have been extensively 
                         reported to cause strong degrading effects on transionospheric 
                         radio propagation at low latitudes, especially over the Brazilian 
                         region, where satellite communication interruptions by the EPBs 
                         have been, frequently, registered. One of the most difficult tasks 
                         for this field of scientific research is the forecasting of such 
                         plasma-depleted structures. This forecasting capability would be 
                         of significant help for users of positioning/navigation systems 
                         operating in the low-latitude/equatorial region all over the 
                         world. Recently, some efforts have been made trying to assess and 
                         improve the capability of predicting the EPB events. The purpose 
                         of this paper is to present an alternative approach to EPB 
                         prediction by means of the use of mathematical numerical 
                         simulation associated with ionospheric vertical drift, obtained 
                         through Digisonde data, focusing on telling beforehand whether 
                         ionospheric plasma instability processes will evolve or not into 
                         EPB structures. Modulations in the ionospheric vertical motion 
                         induced by gravity waves prior to the prereversal enhancement 
                         occurrence were used as input in the numerical model. A comparison 
                         between the numerical results and the observed EPB phenomena 
                         through CCD all-sky image data reveals a considerable coherence 
                         and supports the hypothesis of a capability of short-term 
                         forecasting.",
