Yale researchers will observe, describe, and explain severe atmospheric turbulence over mountains, focusing on 'gravity waves' that impact the stratosphere. The Terrain-induced Rotors Experiment (T-Rex) project aims to measure properties of whirlwinds formed in mountain ranges and monitor gravity wave behavior.
Researchers suggest that high winds over rough terrain can generate acoustic waves that heat the atmosphere at prodigious rates. These waves could account for mysterious 'hotspots' observed above the Andes and Rocky Mountains.
This AGU journal features research on space weather substorms, with a possible explanation for large magnetic fluctuations during the onset of a space weather substorm. Additionally, high frequency sea ice motion may affect Arctic dynamics, while tropical drought regions in global warming and El Nino teleconnections are also explored.
The American Association for the Advancement of Science (AAAS) honored six reporters for their outstanding contributions to science journalism between July 1, 2002 and June 30, 2003. The winners used science storytelling to convey complex issues and make them accessible to the general audience.
Researchers develop waveform templates to analyze gravity wave signals, enabling detection of neutron star collapses and black hole collisions. Gravity waves offer a window to the universe carrying different information than electromagnetic waves.
