240-246The seasonal pattern of equatorial spread-F (ESF) was observed at the magnetic equatorial station Trivandrum and low latitude station SHAR in the Indian sector using ionosonde data. A clearly higher ESF occurrence percentage is observed during vernal equinox compared to autumnal equinox at both locations. Post-sunset vertical drift velocities were observed to be nearly comparable at Trivandrum indicating the comparable electrodynamical forcing on the post-sunset F-layer during the two equinoxes. At the off equatorial station SHAR, post-sunset vertical drift exhibits clear asymmetric pattern, with higher values in the vernal equinox, indicating the possible role of meridional neutral winds in modulating the layer height. The...
