From: Atmospheric resonances and their coupling to vibrations of the ground and waves in the ocean
Predicted buoyancy resonances of a mid-latitude atmosphere and their variability. Frequencies of buoyancy resonances of orders n from 1 to 15 are shown by solid lines, with black lines corresponding to n = 1, in a wide range of trace velocities. Color scale represents the altitude of AGW turning point. The overlaid dashed lines show dispersion curves of infragravity waves in the ocean with depth of 150 m (yellow), 2649 m (red), 4300 m (top white) and 5900 m (bottom white). The background atmospheric temperature and wind velocity profiles used in the simulations are obtained for Wallops Island, Virginia, with the NRLMSISE-00.2 (Picone et al. 2002) and HWM14 (Drob et al. 2015) models for two specific dates corresponding to winter and summer seasons: 15 January 2014 (a–d) and 14 July 2014 (e–h). For each date two times of the day, GMT 06:00 (a, c, e, g) and GMT 18:00 (b, d, f, h), and two directions of the wave propagation, eastward (a, b, e, f) and westward (c, d, g, h) are shown
