Statistical Study of F‐Region Short Period Ionospheric Disturbances Related to Convection in the Lower Atmosphere Over Wuhan, China

Abstract

The ionospheric disturbance is a wave-like plasma activity that impacts remote sensing systems, navigation and positioning, and other long-range communication works. To maintain the safety of human space activities and reduce related economic losses, the study of ionospheric disturbances is necessary and has been a popular topic in space physics.Internal atmospheric dynamics have been identified as one of the main causes of ionospheric disturbances, especially convective activity. The study of the relationship between convective activity and the ionosphere can provide a unique perspective on ionosphere-atmosphere coupling (

The Role of Convectively‐Generated Gravity Waves in Poleward Propagation of MSTIDs Over Srinagar (34.1°N, 74.8°E)

“…Vadas & Azeem (2021) also observed the secondary waves in ionosphere over US from deep convection. Yang et al (2022) also illustrated that the changes in the location of convection and the propagation of GWs also play a significant part in ionosphere-tropospheric coupling.…”

“…The horizontal wavelength of these GWs is observed to be 117 ± 31 km while there phase speeds and time periods are 65 ± 17 m/s and 30 min respectively. Gravity waves in the atmosphere can be triggered by many possible perturbations and tropospheric convective sources are believed to be one of the prominent sources (Vadas, 2007; Yang et al., 2022). Vadas and Nicolls (2012) also pointed out that the GWs originating in troposphere can reach to thermosphere, leading to notable perturbations in the wind and temperature profiles.…”

“…Yang et al. (2022) also illustrated that the changes in the location of convection and the propagation of GWs also play a significant part in ionosphere‐tropospheric coupling. As the GWs in present case are propagating in the NW direction, there must exist any convective source in the SE direction of the location of the imager if these are meant to be convectively generated GWs.…”

Ionospheric TEC Variation and Gravity Waves Signatures During the Solar Eclipse on 21 June 2020 Over Southern China

“…Solar eclipses provide a unique opportunity to study ionospheric disturbances. Several factors can cause ionospheric disturbances, such as geomagnetic variation (J. Lei et al., 2014; Ren et al., 2020), solar radiation events (Padokhin et al., 2019; Yang, Gu, Qin, Teng, Huang, et al., 2022; Yang, Gu, Qin, Teng, Wei, et al., 2022; S.R. Zhang & Coster, 2019), and internal atmospheric dynamics (C.‐S.…”

“…Zhang & Coster, 2019), and internal atmospheric dynamics (C.‐S. Huang et al., 1998; Maurya et al., 2019; Nishioka et al., 2013; K. Wu et al., 2017; Yang, Gu, Qin, Teng, Huang, et al., 2022; Yang, Gu, Qin, Teng, Wei, et al., 2022). Natural hazard events and space weather events such as earthquakes, volcanic eruptions, and solar eclipses can affect the ionosphere by exciting gravity or acoustic waves (Astafyeva, 2019; Chimonas & Hines, 1970; Hegai et al., 2006; John & Kumar, 2013; Meng et al., 2019).…”
