Abstract

The ionosphere is the main error affecting the positioning of the global navigation satellite system. When the ionosphere is strongly disturbed, the ionospheric electron density gradient and its irregularity will seriously affect the overall operation performance of the positioning system and various radio communication systems. As one of the most severe surface weather changes, it is particularly important to study the ionospheric disturbance characteristics during typhoon. Based on the ionospheric Total Electron Content (TEC) data provided by China Earthquake Administration, this paper explores the ionospheric disturbances in Guangdong and Guangxi during the super typhoon Mangkhut 2018. The moving quartile method was used to detect and analyze the ionospheric TEC during the typhoon. The results show that the super typhoon Mangkhut produced abnormal disturbances on the ionospheric TEC in Guangdong and Guangxi from generation to extinction, and produced about 2 TECu negative abnormal disturbances on the day of typhoon generation, and about 2 TECu positive abnormal disturbances on the second day of typhoon upgrading to super typhoon (doy255). Moreover, on the day of the typhoon’s demise, there was a relatively obvious negative anomaly disturbance to the ionospheric TEC near it.
