The Weddell Sea Anomaly (WSA) in ionosphere has been defined by higher electron density at nighttime than during the daytime on summer season near the region of the Weddell Sea.Recent studies show the WSA is an extreme case of longitudinal variation and occurrs all of season except for winter when F10.7 is high. We examine the temporal variation of the WSA using the ground-based GPS TEC measured King Sejong station (geographic latitude 62.2°S, longitude 58.5°W, corrected geomagnetic latitude 48°S) in Antarctic between 2005 and 2009 in condition of solar minimum. We analyze the characteristics of diurnal and semi-diurnal variation for all of years and examine the yearly and seasonal variation of phase and amplitude of the WSA. Our results of local time GPS TEC variation show the amplitudes of the WSA are significant in the summer and its phases appear to be changed according to the season.
