Nonlinear numerical simulation of equatorial spread-F — Effects of winds and electric fields

Recent investigations by means of linear theory revealed the importance of the vertical winds on Rayleigh-Taylor (R-T) instability in the bottomside F-region along with other driving agencies like the zonal electric field and winds. In the present paper, the nonlinear effects of vertical winds and z...

description Recent investigations by means of linear theory revealed the importance of the vertical winds on Rayleigh-Taylor (R-T) instability in the bottomside F-region along with other driving agencies like the zonal electric field and winds. In the present paper, the nonlinear effects of vertical winds and zonal electric fields on the R-T instability are investigated. The results reveal that in the presence of downward wind or/and eastward electric field the evolutionary process of R-T even beyond 350 km altitude where their effects are considered to be less important according to linear theory.
