Turbulence (and not only): The Legacy of Vincenzo Carbone, 2025 Richardson Medal

Turbulence (and not only): The Legacy of Vincenzo Carbone, 2025 Richardson Medal

One year ago, Vincenzo Carbone left us. Vincenzo was a leading scientist in nonlinear geophysics, turbulence, and complex systems, influencing fluid and plasma physics, weather and space weather, solar–terrestrial relations, and climate dynamics. Yet for those who worked closely with him, his legacy goes well beyond his remarkable scientific achievements. Scientific Contributions and Impact Over m ...[Read More]

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

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]

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

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]

Socio-economic and security implications of global heating

Socio-economic and security implications of global heating

This year, like in the last few years, we are experiencing the effects of global heating in increasingly personal ways. The summer of 2022 exposed us to ever more extreme heat waves in North America, Europe, and Asia. For instance, the heat wave in India and Pakistan reached temperatures of 49C in Nawabshah, Pakistan. North America too experienced devastating heat waves and wildfires. Los Angeles ...[Read More]

ECS SpotLight: Changes in the climate dynamics have already modified characteristics and impacts of storms in France: the case study of storm Alex 2020

ECS SpotLight: Changes in the climate dynamics have already modified characteristics and impacts of storms in France: the case study of storm Alex 2020

Extratropical cyclones play a key role in modulating the precipitation and wind in mid-latitudes and can be responsible for extreme wet and windy events. With global warming, the dynamics and thermodynamics associated with these atmospheric systems are being affected. However, due to the complexity of modelling the climate system, a challenge arises when evaluating the influence that climate chang ...[Read More]

ECS SpotLight: Climate change on extreme winds already affects off-shore wind energy availability in Europe

ECS SpotLight: Climate change on extreme winds already affects off-shore wind energy availability in Europe

Off-shore wind energy plays a key role in the transition to a renewable energy (RE) system, and its usage is expected to increase in the next few decades. Nevertheless, wind energy is one of the most variable and weather-dependent RE, because of its natural dependence on the wind speed, which can vary at different time scales, ranging from small-scale turbulence to seasonal oscillations and up to ...[Read More]

Sea level rise: a global threat in a warming planet

Sea level rise: a global threat in a warming planet

Over 70% of the Earth’s surface is covered by seas and oceans but in the geological past the extension of sea and land has varied several times as sea level changed over time. During the past millions of years, the oceans have cyclically retreated and expanded with the alternating of warmer and colder climatic periods in consequence of the astronomical motions of the Earth, repeatedly changi ...[Read More]
