A U.S. study suggests wind blowing over mountain ranges can generate gravity waves that propagate vertically into Earth's upper mesosphere.
Researchers said such waves, known as mountain waves, have previously been observed low in the atmosphere. But Steven Smith, Jeffrey Baumgardner and Michael Mendillo of the Center for Space Physics at Boston University said their research has produced the first unambiguous images of mountain gravity waves in the upper mesosphere -- 50 to 62.5 miles in altitude.
A mass of wind can cause a "gravity wave" when blowing through mountains? Is this the same "gravity wave" that has been long sought-after by LIGO and LISA? Could they detect such a thing?
I plead completely ignorance over this phenomenon, and might try to see if I can get a copy of the paper, which isn't that easy to get based on the access that I have. Can anyone else shed some light into this?
