    Instability Mechanisms for the F‐Region Plasma Irregularities Inside the Midlatitude Ionospheric Trough: Swarm Observations by Yiwen Liu, Chao Xiong, Xin Wan, Yeping Lai, Yuhao Wang, Xiao Yu, Ming Ou

    Published 2021-07-01
    “…Further statistical analysis reveals that the particle precipitation is the dominant mechanism for the dayside MIT region irregularities, while nightside MIT region irregularities are strongly related with the temperature gradient drift instability. The Swarm observations show that the temperature gradient drift instability occur not only in MIT equatorward wall but also in MIT polarward wall, which is different to the theoretical prediction of Hudson and Kelley (1976, https://doi.org/10.1029/JA081i022p03913).…”
