Latest Lee wave Stories
HIAPER was used during the Terrain-induced Rotor Experiment (T-REX) field project. The purpose of T-REX was to study a severe type of atmospheric turbulence--called rotors--that forms near mountains in the California Sierra Nevada range, posing a threat to planes flying in the vicinity. Rotors, which form on the lee side of high, steep mountains, have contributed to a number of aircraft accidents, but scientists know little about their structure and evolution. They are common in the Sierras...
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...
