"Doors held ajar in storms: Insights into Atmospheric Planetary Science"

Our spacecraft have taken us to visit and explore many stark and ancient landscapes in the solar system. At first glance, very little appears to have changed for billions of years, but if we look to the atmosphere we see a dynamism that belies active processes in the present era and that hints at changes at and below the surface. In this talk, we will proceed through these open doors to explore the movement of dust and ice in the hauntingly familiar environment of Mars. We will then travel further to more exotic planetary destinations such as Pluto to see how the atmosphere has sculpted the landscape into eerily familiar forms.
