Abstract. EISCAT radar experiments over a full solar
cycle between January 1984 and March 1995 have been used to construct meridional
neutral wind patterns in the ionospheric F region. For locally geomagnetically
quiet periods the neutral winds have been binned according to season, solar
activity, and universal time. The diurnal and seasonal behaviors and the effect
of the solar flux are described. An empirical model of the meridional neutral
wind for the high latitudes at eight altitudes in the ionospheric F region over
a full solar cycle is presented. Results are compared with other recent
empirical models.
