Graham Cox reports on "Mathematical Paradigms of Climate Science" workshop

Ed Lorenz postdoctoral fellows Graham Cox and Lewis Mitchell recently attended the "Mathematical Paradigms of Climate Science" workshop in Rome, along with MCRN director Chris Jones. The meeting took place at the Istituto Nazionale di Alta Matematica (INDAM), and was organized by Chris Jones in collaboration with Fabio Ancona (University of Padua), Piermarco Cannarsa (University of Rome Tor Vergata) and Alessandro Portaluri (University of Turin).

Each day of the workshop highlighted a specific theme (climate issues, data assimilation and control theory, PDE) with a mix of overview and research lectures, and a discussion session in which participants identified the major issues and future research opportunities that arose from the day's presentations. Among the central topics were: stochastic vs deterministic models; effective model reduction (dimensional reduction vs linearization); parameterization of subgrid-scale processes; sensitivity and stability of climate models.

This structure resulted in many fruitful discussions between mathematicians and climate scientists, and introduced both communities to promising new avenues of research. At the end of the week a committee was appointed to create a list of issues and open problems, to be published in the conference proceedings, which will undoubtedly prove to be a great resource for both current and future researchers in this field.
