From Theory to Impacts: Nonlinear Perspectives on Weather Extremes at UNDERPIN#2

From Theory to Impacts: Nonlinear Perspectives on Weather Extremes at UNDERPIN#2

From 1–5 August 2025, the medieval hilltop town of Erice, Sicily, hosted the second UNDERPIN workshop, a meeting organised within the Nonlinear Processes in Geosciences community and dedicated to advancing the science of weather extremes. The event brought together a truly diverse group of researchers, spanning climate dynamics, attribution science, socio-economic impacts, statistical physics, and ...[Read More]

EGU NP Paper of the Month “Finite-size local dimension as a tool for extracting geometrical properties of attractors of dynamical systems”

EGU NP Paper of the Month “Finite-size local dimension as a tool for extracting geometrical properties of attractors of dynamical systems”

The original goal of this study was to understand how the local dimension of the attractor of a dynamical system could be used to estimate the predictability of the future state of the system, and apply this in the case of radar images of rain. The local dimension using Extreme Value Theory (EVT) has been introduced and used in Faranda et al. (2017) to infer the current predictability of different ...[Read More]

Nonlinear Processes in Earth System Dynamics

Nonlinear Processes in Earth System Dynamics

Earth System Dynamics (ESD) is an open-access EGU journal focussing on an interdisciplinary view of the functioning of the Earth system and global change. Due its broad focus, ESD receives submissions of relevance to several different EGU divisions. Here, I would like to highlight five thought-provoking ESD papers that cover topics spanning environmental governance, extreme events, palaeo-climates ...[Read More]

ECS SpotLight: The link between European warm-temperature extremes and atmospheric persistence

ECS SpotLight: The link between European warm-temperature extremes and atmospheric persistence

Persistent atmospheric circulation patterns are not a necessary requirement for warm temperature extremes in Europe. This key finding from a recent study led by Emma Holmberg challenges a more traditional meteorological view of persistence, which typically considers summertime heatwaves, especially in northern regions of Europe, to be synonymous with persistent atmospheric flow patterns. Furthermo ...[Read More]
