Autor: Guan Le, Guiping Liu, Endawoke Yizengaw, Chin‐Chun Wu, Yihua Zheng, Sarah Vines, Natalia Buzulukova

Publikováno v: Geophysical Research Letters, Vol 51, Iss 10, Pp n/a-n/a (2024)

Abstract We present the observations of field‐aligned currents and the equatorial electrojet during the 23 March 2023 magnetic storm, focusing on the effect of the drastic decrease of the solar wind dynamic pressure occurred during the main phase.

Global Longitudinal Dependence Observation of the Neutral Wind and Ionospheric Density Distribution

Autor: Endawoke Yizengaw

Publikováno v: International Journal of Geophysics, Vol 2012 (2012)

The statistical global view of the low-latitude ionospheric density stimulates further interest in studying the strong longitudinal variability of the ionospheric density structures in low-to-equatorial latitudes. However, we are not completely certa
