The auroral feature, first spotted by amateur astronomers in 2015, likely traces high-altitude atmospheric waves.
New high-resolution imaging and modeling reveal the first evidence of enhanced turbulence due to gravity wave modulation of Kelvin-Helmholtz instabilities.
A thunderstorm made waves on a rare “bright night.”
Gravity waves play a key role in driving upper atmosphere circulations but are poorly understood. New high-resolution simulations are resolving complex wave behaviors with unprecedented detail.
Not to be outdone by the discovery of STEVE sub-auroral emissions last year, citizen scientists across Scandinavia reveal dune-shaped optical features, a new atmospheric phenomenon.
In a new study, the enigmatic gravity waves were seen most frequently at equatorial latitudes and propagating from the winter to the summer hemisphere.
How does vertical wind shear impact the characteristics of gravity waves generated by tropical cyclones?
One research group studied noctilucent clouds at large distances from a different point of view, using cameras aboard a meteorological balloon that sailed into the stratosphere.
Polar vortices play a central role in coupling the atmosphere from the ground to the middle atmosphere. New satellite diagnostics describe mesospheric polar vortices and coupling to lower altitudes.
New study reveals complex behavior of gravity waves in the atmosphere.
