The authors study the Equatorial Spread F, by looking at its correlations with vertical winds and electric fields. Present theory relates the ESF to Rayleigh-Taylor instability mechanisms. Here the authors develop correlations between the spread of the ESF and the presence and activity of downward winds and electric fields. As a consequence of this study they conclude that the ESF extends beyond the height normally ascribed to it by linear theories. Daily variations in the vertical winds could be responsible for the variations seen in the ESF.
