F-region neutral winds from ionosonde measurements of h/sub mF2/ at low-latitude magnetic conjugate regions

Technical Report ·
OSTI ID:6135838

The behavior of the F2-peak height difference, delta h/sub F2/, between low-latitude magnetic conjugate points, is known to be governed by thermospheric winds blowing along the magnetic meridian. Ground-based ionosonde measurement of h/sub m F2/, at two pairs of magnetic conjugate stations, were analyzed in conjunction with the results of a realistic dynamic computer model of the tropical ionospheric F-region, to determine thermospheric wind velocities. The behavior of monthly average values of the sun, at conjugate points, of the thermospheric horizontal wind velocity component in the magnetic meridian, at low latitudes, is inferred for months of solstice and equinox, as well as for periods of low and high solar activity.
