New class of atmospheric waves, producing strong temperature ripples, discovered over Antarctica

Researchers from the University of Colorado Boulder discovered a new class of mesospheric waves by observing the high parts of the atmosphere over Antarctica. These waves seem to send constant ripples through the Earth's atmosphere and probably affect high-level winds, climate and Earth-based communications systems.

Newly discovered waves sweep through the mesosphere, the part of Earth's atmosphere beginning at an altitude of about 48 km (30 miles), every 3 to 10 hours, causing significant temperature fluctuations in a short time span.

"These waves are very large perturbations, causing up to 100-degree Fahrenheit changes in temperature in less than five hours, and every time we look, we see them," said lead author Cao Chen, a Ph.D. student in the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences (CIRES) and Aerospace Engineering Sciences department.
