Cloud cover in the midlatitudes plays an important role in the Earth’s radiative balance. The heating associated with the clouds might also impact atmospheric circulation. On the other hand, it has long been accepted that organized atmospheric circulation systems such as fronts, anticyclones, and cold air outbreaks all can generate clouds. However, a robust characterization of the role of clouds in climate variability, especially over the oceans, has only recently been made possible due to an expanding observations network. At this time, there is an ever-expanding set of literature on the behavior and trends of midlatitude clouds and their representation in numerical weather and climate models. Therefore, this session seeks to bring together and report on recent research on the physics of midlatitude clouds and the relationship between the clouds and climate variability. The session seeks to span multiple temporal and spatial scales, with an interest in understanding the relative roles of: (i) boundary layer processes, (ii) synoptic circulation, and (iii) microphysics. The session also invites studies that focus on how cloud radiative forcing can impact local and remote atmospheric dynamics.
