                         latitude location, Cachoeira Paulista. Over the latter location 
                         the spread-F seems to occur only in association with vertically 
                         extended flux tube-aligned plasma bubble development over the 
                         equator. The present study shows that the threshold conditions at 
                         the F-layer height and ionization vertical drift for plasma bubble 
                         generation and growth over the equator are different from those 
                         required for the production of equatorial bottomside spread-F 
                         only. Conditions of the F-layer dynamo-induced eastward electric 
                         field evening enhancements for these cases are briefly 
                         discussed.",
