About the Cover

This photo, captured from the International Space Station, shows Hurricane Florence as it made landfall in North Carolina on 14 September 2018. The category 1 storm killed 52 people and caused some $24 billion in damages. On page 28 , Caroline Muller and Sophie Abramian dive into how multicloud structures such as Florence are formed in the atmosphere and what advances have been made in observing and simulating cloud dynamics and convective storm systems.
