Traveling Ionospheric Disturbances in the Vicinity of Storm-Enhanced Density at Midlatitudes. [PDF]

J Geophys Res Space Phys, 2022
AbstractThis study provides first storm time observations of the westward‐propagating medium‐scale traveling ionospheric disturbances (MSTIDs), particularly, associated with characteristic subauroral storm time features, storm‐enhanced density (SED), subauroral polarization stream (SAPS), and enhanced thermospheric westward winds over the continental ...

Model of traveling ionospheric disturbances [PDF]

Journal of Space Weather and Space Climate, 2013
A multiscale semi-empirical model of traveling ionospheric disturbances (TIDs) is developed. The model is based on the following assumptions: (1) TIDs are generated by acoustic-gravity waves (AGWs) and propagate as pressure waves; (2) time intervals ...

Understanding Inter-Hemispheric Traveling Ionospheric Disturbances and Their Mechanisms [PDF]

Remote Sensing, 2020
Traveling ionospheric disturbances (TIDs) are wave-like disturbances in ionospheric plasma density. They are often observed during both quiet (medium-scale TID) and geomagnetically disturbed (large-scale TID) conditions. Their amplitudes can reach double-

Spectral investigation of traveling ionospheric disturbances: IONOLAB-FFT

Geodesy and Geodynamics, 2017
Ionosphere is an important layer of atmosphere which is under constant forcing from both below due to gravitational, geomagnetic and seismic activities, and above due to solar wind and galactic radiation. Spatio-temporal variability of ionosphere is made

Pilot Ionosonde Network for Identification of Traveling Ionospheric Disturbances

Radio Science, 2018
AbstractTraveling ionospheric disturbances (TIDs) are the ionospheric signatures of atmospheric gravity waves. Their identification and tracking is important because the TIDs affect all services that rely on predictable ionospheric radio wave propagation.

N-dimensional Lomb Scargle Periodogram analysis of traveling ionospheric disturbances using ionosonde data

Frontiers in Astronomy and Space Sciences
There is a multitude of wave-like phenomena in Earth’s ionosphere and thermosphere such as acoustic waves, gravity waves, planetary waves, tides, and Traveling Ionospheric Disturbances (TIDs) which are the ionospheric manifestation of atmospheric waves ...

Parameters of traveling ionospheric disturbances: results from spaced oblique HF sounding

Вісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2022
Urgency. A characteristic feature of the ionospheric radio channel is that its parameters depend on season, local time, solar activity, geographic coordinates, the state of the sun, the state of atmospheric-space weather, etc. The state of the atmosphere

Periodic oscillations of Doppler frequency excited by the traveling ionospheric disturbances associated with the Tonga eruption in 2022

Earth, Planets and Space, 2023
The explosive eruption of the Hunga Tonga-Hunga Ha’apai volcano on 15 January 2022 generated atmospheric waves traveling around the Earth, which caused ionospheric disturbances on various spatio-temporal scales.
