[ Watch the Video: Catching Some Venus Waves ] Brett Smith for redOrbit.com - Your Universe Online Planetary scientists have known that the atmosphere on Venus acts more like a river or ocean than Earth’s atmosphere and a new study based on data from the European Space Agency (ESA) has found that the physical features of Venus’ surface play a role in the circulation of this atmosphere. The new study focused on Venus’ lower atmosphere, which is capped by a dense cloud layer that...

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...

Atmospheric waves that ripple through clouds could spin up tornadoes when a thunderstorm gets in the way, new research shows. Tornadoes generally form in the late spring when warming temperatures make the air unstable (though they've been known to pop up at other times of the year). The classic tornado-forming scenario features a layer of warm, moist air trapped under a layer of cold, dry air. If this balance is upset, say by warming at the surface, the moist air rises, cools and...

Did you know that there's a new breakfast food that helps meteorologists predict severe storms? Down South they call it "GrITs." GrITs stands for Gravity wave Interactions with Tornadoes. "It's a computer model I developed to study how atmospheric gravity waves interact with severe storms," says research meteorologist Tim Coleman of the National Space Science and Technology Center in Huntsville, Alabama. According to Coleman, wave-storm interactions are very important. If a gravity wave hits...
