The first seminar of the new global online seminar series on Mathematics of Climate will take place on Tuesday November 3rd, 9am Los Angeles time, 5pm London time, 6pm Paris time.
We will have the pleasure to listen to Darryl Holm from Imperial College London. The title of his talk is: Applying Kelvin’s circulation theorem in climate science.
The abstract and the connection information follows this message.

Abstract:
The prediction of climate change and its impact on extreme weather events is one of the great societal and intellectual challenges of our time. It has three parts:
1. Make the distinction between weather and climate.
2. Understand the dynamics of the fluctuations of the physical variables.
3. Predict how the variances of the fluctuations are affected by statistical correlations in their fluctuating dynamics.
This seminar investigates a stochastic geometric mechanics framework called LA SALT which can at least formally meet all three parts of the challenge for the problem of climate change, given a deterministic fluid theory derived from the variational principles of geometric mechanics.
