“…Though, the traditional ground-based measurements (e.g., Sethi and Mahajan, 2002;Sun et al, 2012) are sufficient to determine the bottom-side ionospheric behaviour, the modern space-based measurements (Aragon-Angel et al, 2009) are essential to attest the topside variability in precise manner (Reinisch and Huang, 1998). Due to the coincidence of Tropical Cyclone (TC) with geomagnetic storm the authors in Afraimovich et al (2008) could not manage to detect the disturbance due to the generation of typhoon SAOMAI. Lin (2012aLin ( , 2012b, Polyakova and Perevalova (2013) and Tian et al (2010) also have analyzed the TEC variations in the low-latitude ionosphere during typhoons.…”

“…GPS measurements provided a new opportunity to observe the ionospheric response to typhoons (Afraimovich et al., 2008; Li et al., 2017, 2018; Polyakova & Perevalova, 2011, 2013; Zakharov and Kunitsyn, 2012; Zakharov et al., 2019). The action of typhoons was established to be accompanied by the generation of quasiperiodic perturbations with periods, T , shorter than 20 min and T ≈ 20–30 min, and the long wavelength disturbances to have a larger amplitude, which was shown to correspond to the greater power of typhoons.…”

We have acquired HF Doppler measurements and studied the dynamics of the ionosphere in the ∼100–300 km altitude range during the 1–10 September 2019 period of typhoon activity near the People's Republic of China (PRC). The multifrequency multiple path system located at the Harbin Engineering University campus, the PRC, and probing the ionosphere at oblique incidence was used to identify the effects from the typhoons. The response of the ionosphere to the Typhoon Lingling was detected along three adjacent radio‐wave propagation paths where chaotic and quasiperiodic variations in the Doppler shift and a significant (from −1 to 1 Hz or greater) Doppler spectrum broadening were observed to occur. The Doppler spectrum chaotic variations are due to plasma turbulence generated by typhoons in the ionosphere, and the Doppler shift quasiperiodic variations along the main ray are due to infrasound and atmospheric gravity waves (AGWs) launched by the typhoons. The relative amplitude of quasiperiodic variations in the electron density in the field of the infrasound wave reached several percent, and in the field of the AGW attained from ten to a few tens of percent. The effects of the Typhoon Faxai during 9/10 and 10/11 September 2019 nights were accompanied by a 27% decrease in the electron density in the ionospheric E and F regions. At the closest approach of the Typhoon Faxai to the ionosonde during 8/9 September 2019 night, when it had the largest energy, a 56% increase was detected in the ionospheric F region electron density.

“…Solar and geomagnetic activities together with geohazards (e.g., earthquakes and typhoons) may cause the oscillations of electron densities in the ionosphere. Numerous studies have shown a close relationship between intense solid-Earth activities (such as volcanos, earthquakes, tsunamis, or typhoons) and ionospheric disturbances [1][2][3][4]. As typical and complex strong weather systems in the lower atmosphere, typhoons can excite gravity waves and propagate to the upper layers of the ionosphere, causing several disturbances [3].…”

As typical and complex strong weather systems in the lower atmosphere, typhoons can excite gravity waves and propagate to the upper layers of the ionosphere, causing several disturbances [3]. As early as 1958, Bauer [5] studied the response of the ionosphere during hurricane transit and found that the ionospheric F2-layer critical frequency (foF2) increased during hurricane transit, and the frequency reached the maximum value when it was closest to the observation station.…”

Typhoons often occur and may cause huge loss of life and damage of infrastructures, but they are still difficult to precisely monitor and predict by traditional in-situ measurements. Nowadays, ionospheric disturbances at a large-scale following typhoons can be monitored using ground-based dual-frequency Global Positioning System (GPS) observations. In this paper the responses of ionospheric total electron content (TEC) to Typhoon Maria on 10 July 2018 are studied by using about 150 stations of the GPS network in Taiwan. The results show that two significant ionospheric disturbances on the southwest side of the typhoon eye were found between 10:00 and 12:00 UTC. This was the stage of severe typhoon and the ionospheric disturbances propagated at speeds of 118.09 and 186.17 m/s, respectively. Both traveling ionospheric disturbances reached up to 0.2 TECU and the amplitudes were slightly different. The change in the filtered TEC time series during the typhoon was further analyzed with the azimuth. It can be seen that the TEC disturbance anomalies were primarily concentrated in a range of between −0.2 and 0.2 TECU and mainly located at 135–300° in the azimuth, namely the southwest side of the typhoon eye. The corresponding frequency spectrum of the two TEC time series was about 1.6 mHz, which is consistent with the frequency of gravity waves. Therefore, the upward propagating gravity wave was the main cause of the traveling ionospheric disturbance during Typhoon Maria.
