Abdu, M.A., Iyer, K.N., de Medeiros, R.T., Batista, I.S. and Sobral, J.H.A. (2006). Thermospheric meridional wind control of equatorial spread F and evening prereversal electric field. Geophysical Research Letters 33: doi: 10.1029/2005GL024835. issn: 0094-8276.

The role of the evening prereversal zonal electric field enhancement (PRE) as conducive to equatorial spread F (ESF)/plasma bubble development versus that of the magnetic meridional wind as a suppressing factor is examined using digital ionosonde data from an equatorial site, Sao Luis (SL), and a low latitude site, Cachoeira Paulista (CP) in Brazil. The evening vertical plasma drift (Vz) over SL is used, together with the F layer peak height (hmF2) over CP, to compute the magnetic meridional wind. The analysis performed for two epochs, that is, March-April of 1999 and 2001, provide consistent evidence that the magnetic meridional wind can negatively influence the ESF development in two ways: (a) by reduced development of the PRE and. (b) by direct suppression of the bubble growth
