The aim of the group is to
enhance the understanding of the dynamics and nature of phenomena that
occur in the atmosphere on meso to global scales and that are important
in weather and climate. This aim is pursued using a combination of
theory, diagnostics of observations and the design, execution and
diagnosis of experiments using a range of numerical models.
Phenomena of current interest in middle latitudes include storm-tracks, blocking, cyclones and teleconnections. In lower latitudes, the subtropical anticyclones-monsoon system, the water vapour distribution and the organisation of tropical heating are all being investigated. Rossby wave propagation, potential vorticity and a Lagrangian perspective all continue to play a role in the diagnostic work of the group.
