The mesosphere ranges from 31 to 53 miles (50 ... AWE started observing in November 2023, and the Helene gravity-wave images are among the first AWE images that NASA has released publicly.

Gravity waves (GWs) are oscillations in the atmosphere ... located above the troposphere and below the mesosphere, where temperature increases with altitude. Mesosphere: The layer of the ...

Although they don't impact the surface directly, historical evidence and simulations suggest airbursts can pack a punch.

Gravity Waves (GWs): Oscillations in the atmosphere caused by the buoyancy of air parcels, often resulting from disturbances such as wind or topography. Mesosphere: A layer of the Earth's ...

26, 2024, AWE observed atmospheric gravity waves generated by Hurricane Helene ... of infrared light produced by airglow in Earth’s mesosphere. The small black circles on the continent mark ...

Atmospheric tides generate winds of up to 100 metres per second in the mesosphere. In the stratosphere, winds are decelerated by the breaking of gravity waves generated e.g. by wind overflowing ...
