Polar Vortices: Earth, Mars, and beyond

A common feature of the atmospheres of terrestrial planets, including Earth, Mars, Venus and Titan, is the existence of polar vortices (strong circumpolar winds at mid- and high latitudes). These polar vortices are the location of unique chemical and dynamical processes that have a global impact on these planets. Here, I will discuss a series of studies examining the dynamics and transport of polar vortices on Earth (modern and paleo), Mars, Titan, and hypothetical planets.
