                         the low-latitude location Cachoeira Paulista (22 degrees S, 45 
                         degrees W, magnetic latitude = 15 degrees S), are compared with 
                         their values calculated by the Sheffield University 
                         Plasmasphere-Ionosphere Model(SUPIM)to determine the vertical 
                         (ExB)drift velocity at the equator and the magnetic meridional 
                         wind velocity over the two locations. The calculated and observed 
                         values of f(0)F(2)are then matched at both Fortaleza and Cachoeira 
                         Paulista to obtain the magnetic meridional winds over their 
                         respective conjugate locations. To account for the observed 
                         f(0)F(2)diurnal variation pattern over Cachoeira Paulista, it was 
                         found necessary to include a small source of ionization, 
                         attributable to energetic particle precipitation in the South 
                         Atlantic anomaly region. The vertical drift velocity and magnetic 
                         meridional wind velocity derived for summer months during both 
                         solar minimum and solar maximum are compared with their values 
                         given by other published models. While the diurnal variation of 
                         the modeled vertical drift velocity shows general agreement with 
                         the values based on Jicamarca radar measurements (the exception 
                         being during the sunset-midnight period at solar maximum and 
                         between 2000-2300 LT at solar minimum), the magnetic meridional 
                         wind shows significant differences with respect to the Horizontal 
                         Wind Model 1990 (HWM90)[Hedin et al., 1991]during both solar 
                         minimum and solar maximum at Fortaleza and at locations conjugate 
                         to Fortaleza and Cachoeira Paulista.",
