Fig. 6From: Simulation study of atmosphere–ionosphere variations driven by the eruption of Hunga Tonga-Hunga Ha’apai on 15 January 2022Neutral wind velocities at 11:15 UT. a Horizontal velocity, and b vertical velocity. To illustrate small velocities clearly, logarithms of the velocities in the unit of cm/sec are taken. Positive sign indicates outward in a and upward and b, respectively. Locations of Lamb wave and Pekeris wave are indicated in a as “L” and “P”, respectivelyBack to article page
