摘 要：An ionospheric positive storm on 13 October 2016 was *** longitude effect of ionospheric storm along 40°N latitude region is studied with 23 GPS stations from 0°E to 360°*** electron content(TEC) was calculated with polynomial method,and TEC difference between the storm time and quiet time(ΔTEC) were *** variations of TEC difference were different at different *** was a positive phase storm at the local time day side region,while the variations were not obvious at the night side *** maximum value of ΔTEC was about 25 TECU at 330°E at about 1400 UT on 13 October *** Ionosonde data at EB040(0.5 °E,40°N) and RL052(51.5 °N,359.4 °E) were also used to study the ionospheric *** Δfo F2 of RL052 increased earlier that low latitude ionosonde of *** was a second peak of ΔTEC at the local night time about 2000 LT on 13 October *** latitude effect of ionospheric storm was also studied with 7 GPS stations at 0°E *** was found that the positive storm was obvious at high latitude region,while it was weak at low latitude *** phenomenon may be caused by the fountain *** high latitude to low latitude,ΔTEC gradually began to increase,and ΔTEC at higher latitude reached the maximum value earlier than the low *** show that the positive ionospheric storm may be caused by the equatorward surge.
