On Wednesday, August 6, from 2:00 to 3:00 pm MT, join NSF NCAR’s High Altitude Observatory (HAO) for a talk entitled "Modeling of Secondary Gravity Waves in the Mesosphere and Lower Thermosphere."
The seminar focuses on secondary gravity waves (SGWs), which are generated through the dissipation and breaking of primary waves. These waves are significant in the mesosphere, lower thermosphere (MLT), and thermosphere-ionosphere system. Dr. Wenjun Dong will discuss key generation mechanisms, including linear responses to primary wave momentum deposition, wave packet self-acceleration, nonlinear dynamics from wave breaking, and instabilities. The talk will also highlight recent progress in applying artificial intelligence (AI) to the simulation of gravity waves and global atmospheric dynamics, as well as the potential and challenges of incorporating AI-based approaches into gravity wave parameterizations for global climate and weather models.
