Equatorial travelling ionospheric disturbances (TIDs) compared with midlatitude TIDs
2011 XXXth URSI General Assembly and Scientific Symposium, 2011A spaced radio experiment for measuring the motions of F-region TIDs has been operated in Brazil since March 2010. The location is near the easternmost tip of Brazil at 7 deg. south latitude or about −11 deg. geomagnetic lat. These are the first systematic measurements of TIDs near the equator.

Conjugate effects in the generation of travelling ionospheric disturbances (TIDs) in the F-region
Planetary and Space Science, 1983A rapid onset of auroral absorptions was simultaneously recorded by a chain of standard riometers, situated in the northern and southern magneto-conjugate areas, during a period of pronounced substorm activity. The first absorption peak was followed by sequential disturbance patterns in the occurrence of the F-region parameters, virtual height (h′F ...

Traveling ionospheric disturbances (TIDs) at mid‐latitudes: Solar cycle phase dependence
Radio Science, 1988Faraday observations of total electron content (TEC) at Haifa, Israel (32.87°N, 35.09°E), during periods near the maximum (1980) and minimum (1984) phases of the current solar cycle have yielded information about the structure and variability of the ionosphere during both epochs in general, and about traveling ionospheric disturbances (TIDs) in ...

Abstract In this paper, the occurrence of tides, large-scale travelling ionospheric disturbances (LSTIDs) and medium-scale travelling ionospheric disturbances (MSTIDs) at mid-latitudes is investigated with respect to different geomagnetic conditions described by the K-index.

A study has been undertaken on the conjugate effects in the generation and propagation of large scale ionospheric disturbances (LSTIDs), as deduced from the virtual height (h′F) rises obtained from ionosonde chains in the Japanese and Australian longitudinal sectors.

Abstract : Travelling ionospheric disturbances in the ionized regions of the earth's atmosphere have been investigated using a CW doppler (phase-path) sounding array. A description of wave characteristics such as periods and wavelengths for medium scale TID's is given.

Abstract Geomagnetic storms are typically accompanied by ionospheric or thermospheric disturbances, yet the response of metal layers to storms requires further investigation. Jiao et al. (2025, https://doi.org/10.1029/2024gl113941 ) show that equatorward neutral winds at 250
