Mars' Middle Atmosphere: Gravity Waves Reign Supreme
2025-03-11
A groundbreaking study reveals that unlike Earth, Mars's middle and upper atmosphere circulation is primarily driven by gravity waves (GWs), not Rossby waves. Analysis of long-term atmospheric data shows GWs facilitate rapid vertical transfer of angular momentum, significantly influencing north-south circulation. This contrasts with Earth's stratosphere, resembling the mesosphere instead. This finding necessitates refining existing Martian atmospheric models for improved climate and weather simulations, crucial for future missions. Future research will explore the impact of Martian dust storms on this dynamic, promising more accurate Martian weather forecasting.
