The observation of ionospheric large-scale wave structure in Southeast Asia

The occurrence of the equatorial plasma bubble (EPB) at nighttime always leads to the scintillation and fluctuation of radio wave signals from satellites. The observation in the seeding perturbation of EPB is important to understand the seeding mechanism of EPB. In this paper, a large-scale wave str...
