Title: Extreme events of the mid-latitude atmospheric circulation: A dynamical systems perspective Authors:  Davide Faranda - CNRS (France) [presenting]
Abstract: The link between rare recurrences of states in dynamical systems and the extreme value theory is explored. Statistics is used to infer important properties of the system such as the distribution of local dimensions (entropy) and the stability of all accessible states. We apply this framework to weather reanalysis data, the daily NCEP 1948-2015 sea level pressure (SLP) fields over the North Atlantic. We show that extremes in the local (daily) dimensions and in the stability of SLP fields are related to climate extremes such as historical storms and blocking.
