We compare the southward directed neutral meridional wind and the nighttime ion density simultaneously measured on AE-E for altitudes from 250 to 290 km and find them to correlate when the magnetic field inclination is negative and anticorrelate when the inclination is positive. This effect is attributed to neutral winds transporting the ions up or down a field line depending upon the sign of the field-aligned wind and the inclination. Model calculations for the ion density in the presence of a field-aligned wind and ambipolar diffusion are presented. Six examples of this ionospheric response are analyzed and found to be qualitative and approximate agreement with the theoretical results.
