Fig. 4

Height‒latitude distribution of the simulated meridional wind perturbation along the 175º E longitude sector on 15 January 2022 at 06 UT (a), at 08 UT (b), and at 10 UT (c). Red arrows indicate the Lamb wave. A red asterisk indicates the location of the Hunga-Tonga volcano. The meridional wind variation is shown by taking the difference of TEC with and without the Hunga-Tonga eruption
