The state of the atmosphere on Earth can have big impacts on both human health and society. As an example, fog is a low lying cloud that can cause major disruptions to human activity. However, fog is difficult to forecast as there are multiple physical processes that all interact non-linearly. A process that is fog microphysics, and in particular, how aerosol particles are key in the formation and development of nocturnal fog. In Craig’s talk, he will give an overview of what we know about aerosol-fog interactions, how better physical representation can improve fog simulations and how understanding aerosol-fog interactions is critical when investigating fog in polluted regimes such as Northern India. However, how are atmospheres different from Earth at the cold outer edges of our solar system? The ice giants, Uranus and Neptune, have extreme temperatures and weather that we can observe using infrared telescopes in space and on the ground. In Naomi’s talk, she will give an overview of what we know about the middle atmospheres of these relatively unexplored planets and how we are planning to find out more in the future.
