EXCERPT: Quite by accident, a group of physicists based at Colorado State University has detected gravity waves rippling across Earth's highest atmospheric layers. The find [...] is the first time that the phenomenon has been observed so far above the planet's surface on a global scale and with a high amount of spatial detail. The newfound detection ability may mean big things for weather and climate forecasting. [...] The "global climatology" of gravity waves has been well-documented for the middle atmospheric layers of Earth, but the upper atmosphere has been more elusive. This enforces a limitation on complete models of global atmospheric circulation and, thus, on global climate models....
