Description:
The ionospheric condition can be affected by the factors from above (solar flare, geomagnetic storm, etc.) and below (volcanoes, earthquake, severe weather disturbance, etc.). To distinguish these sources from ionospheric observations is important for understanding the ionospheric variability and is practically necessary for the ionospheric forecast. During the period from 21 Aug to 24, 2017, a tropical depression over the east of Luzon was formed, and with its moving along the west direction it intensified rapidly and soon developed a Super Typhoon named Hato. Hato made landfall in the south coast of Guangdong, China, on 23 Aug. 2017. During its landfall period, the ionospheric TEC in south China experienced large increase. It is noted that a weak geomagnetic storm also occurred in the landfall day. So, to determine the reasons of this large increase became very interesting. Based on TEC data derived from the dense distributed GNSS data near the landing area, the meteorological and geomagnetic storm data, the ionospheric variation are analyzed carefully to determine the source of this TEC enhancement, also to clarify this Typhoon’s effect on the ionosphere.
