From: First observational study during a solar eclipse event on variations in the horizontal winds simultaneously in the troposphere-stratosphere-mesosphere-lower-thermosphere region over the equatorial station Thumba (8.5°N, 77°E)

Fig. 8.

Height profiles of (a) amplitude, and (b) phase, of the dominant 80-minute-period gravity wave observed in zonal winds. (c) and (d) are the same as (a) and (b) but for meridional winds. The dotted inclined line indicates the downward and upward propagation of the wave.
