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]

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]

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]

NPG Paper of the Month: “A Range of Outcomes: The Combined Effects of Internal Variability and Anthropogenic Forcing on Regional Climate Trends over Europe”

May 19, 2023

The NPG paper of the month for February 2023 was awarded to “A Range of Outcomes: The Combined Effects of Internal Variability and Anthropogenic Forcing on Regional Climate Trends over Europe” by Clara Deser and Adam S. Phillips. How much will Europe warm in the next 50 years? Will precipitation increase or decrease? Are past climate trends unique or could alternate realities have exis ...[Read More]
