A Study of TEC Storm on 13 October 2016ober 2016. The latitude effect of ionospheric storm was also studied with 7 GPS stations at 0°E meridian. It was found that the positive storm was obvious at high latitude region, while it was weak at low latitude region. This phenomenon may be caused by the fountain effect.
