Neutral Winds and Electric Fields from Model Studies Using Reduced Ionograms.
Abstract
A relationship between the vertical component of the ion velocity and electron density profiles derived from reduced ionograms is developed. Methods for determining the horizontal components of the neutral winds and electric fields by using this relationship and making use of the variations of the inclinations and declinations of the earth's magnetic field are presented. The effects that electric fields have on the neutral wind calculations are estimated to be small but not second order. Seasonal and latitudinal variations of the calculated neutral winds are given and it is shown that these are in general agreement with results from current theoretical models and from measurements. In particular, the midnight reversal of the meridional wind at Arecibo is observed from these calculations.
