Abstract:

The interaction between lower atmospheric forcing and middle atmospheric wave dynamics plays a critical role in shaping global climate and weather patterns. This study examines key mechanisms such as gravity wave propagation, planetary wave breaking, and large-scale climate phenomena like ENSO and monsoonal circulations, which influence stratospheric wind patterns, sudden stratospheric warming (SSW) events, and long-term atmospheric circulation changes. Using satellite data, radiosondes, and numerical models, we analyze how lower atmospheric disturbances impact wave activity and stratosphere-troposphere coupling. Findings indicate that climate change is altering wave propagation patterns, affecting global circulation and weather predictability. Advances in AI-driven forecasting, improved wave parameterization in climate models, and long-term observational strategies are essential for enhancing our understanding of atmospheric dynamics. This research contributes to improved climate models, extreme weather forecasting, and global climate change assessments, aiding in better preparedness for atmospheric variability and extreme events.
