Clear wave structures were visible in the clouds and time-lapse photography was used to derive the parameters characterising the gravity waves which could account for the observed NLC modulation. Using two nearby atmospheric radars, the Esrange MST Radar data and Andoya MF radar, we have ...
Ray C. took a picture just outside of Uniontown, Pennsylvania, where you can see the clouds are lined up in neat rows, sort of like a cornfield. Ray wanted to know what was going on to make these clouds happen. (Photo Provided) They are called "Gravity Waves." Think of gravity ...
However, occasionally the wave packets triggered irreversible changes to the clouds, which transformed from closed mesoscale cellular convection to open form. In this paper we use large eddy simulation (LES) to examine the physical mechanisms that cause this transition. Specifically, we examine whether...
Northwesterly winds racing across Quebec and the Maritimes rose up and over both the Laurentians and the Appalachians, triggering the waves we can see in the clouds this weekend. WATCH: How experts spot turbulence ahead of your next flightRelated...

In addition, the cloud slopes with time are greater for the thicker weaker clouds at higher altitudes than the thinner stronger clouds at lower altitudes. Gravity-wave signatures are routinely observed in the cloud detections. Upon estimating stratospheric wave activity in the data, we observed ...
Her influential discovery never earned Rubin a Nobel Prize, but scientists began looking for signs of dark matter everywhere, around stars and gas clouds and among the largest structures in the galaxies in the Universe… But… over the past half century, no one has ever directly detected a sin...

In subject area: Earth and Planetary Sciences Gravity waves are oscillations in the atmosphere that are caused by the force of gravity and can be measured using radar. They can form patterns, such as mountain waves, and are also associated with jet streams. ...
