Polarization fields produced by winds in the equatorial F-region

On the nature of low‐latitude Es influencing the genesis of equatorial plasma bubble

“…A verification of this possibility, however, requires spatial measurements of E region conductivity for which we have no experimental evidence. Based on simulation, it was shown by Fesen et al [2000] that electron densities greater than 10 4 electrons/cm 3 preclude the PRE by short-circuiting the F region dynamo field [Rishbeth, 1971], the primary driver of the PRE. Therefore, the observed difference in the postsunset height rise of the F region mentioned earlier can be explained on the basis of E s observations from low latitude.…”

Magnetic storm effects on the tropical ultraviolet airglow

“…Very few measurements of the meridional and zonal components of the neutral wind have been made at low latitudes (see Bedinger [1970] and references therein). Concerning the zonal component, Woodman [1972] suggested that the eastward E x B plasma drift observed at the magnetic equator at night is due to an eastward F region wind [Rishbeth, 1971] …”

Simulation of the pre‐reversal enhancement in the low latitude vertical ion drifts

“…The PRE signals an enhancement in the eastward electric field just before it reverses to westward in the early evening and is generally attributed to the F region dynamo [e.g., Rishbeth, 1971Rishbeth, , 1981 Model Description …”
