The large scale circulation plays a fundamental role in driving, or facilitating, extreme weather. Our past and present research include contributions to extreme weather from various dynamical processes. These include various aspects of Rossby wave dynamics, and jet stream dynamical regimes. Some of the research is part of the EDIPI project.
