Tommaso Alberti

I am a researcher at the Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Rome, Italy. My research activity is focused on data analysis and modeling, via dynamical system and statistical mechanics approaches, to understand complexity in geoscience and near-Earth space plasma. My interests cover: - Complexity and chaos in geosciences - Extreme events in geosciences - Sea level variability: transient phenomena, long-term variability and trends - Geo-electromagnetic transient phenomena and effects on electric infrastructures - Turbulence in fluids and plasmas

NP Campfire: “Perspectives on Climate Science: from historical developments to research frontiers”

Recently, the European Geosciences Union (EGU) started to support a new type of event called ‘Campfires’ that will give the Divisions the freedom to run online interactive events in a way that suits their needs. This allows the EGU Divisions to encourage interactions in their research communities through virtual informal meetings. In this framework, and thanks to a group of young and established s ...[Read More]

NPG Paper of the Month: “Statistical postprocessing of ensemble forecasts for
 severe weather at Deutscher Wetterdienst”

NPG Paper of the Month: “Statistical postprocessing of ensemble forecasts for
 severe weather at Deutscher Wetterdienst”
Probabilities of wind gusts higher than 14 m/s on
a regular 1 km grid over Germany; 13 h forecast lied time from Ensemble-MOS for COSMO-DE-EPS from 29 October 2018. Licence: Statistical postprocessing of ensemble forecasts for severe weather at Deutscher Wetterdienst.

The October 2020 NPG Paper of the Month award goes to Reinhold Hess for the paper “Statistical postprocessing of ensemble forecasts for 
severe weather at Deutscher Wetterdienst“. Ensemble Forecasting rose with the understanding of the limited predictability of weather. In a perfect ensemble system, the obtained ensemble of forecasts expresses the distribution of possible weather scena ...[Read More]

The September 2020 NPG Paper of the Month award goes to Dylan Harries and Terence J. O’Kane for their paper “Applications of matrix factorization methods to climate data” (https://doi.org/10.5194/npg-27-453-2020). Dylan is a postdoctoral fellow within the Oceans and Atmosphere business unit of CSIRO (Australia). His current research focuses on methods for learning reduced-order models from d ...[Read More]

Perspectives on Climate Science: from historical developments to research frontiers

Breaking news: a bizarre early-September snowstorm dumped snow from Montana to New Mexico, a medicane hit Southern Italian regions and Greece, heatwaves and droughts are expected to increase in the future… These extreme events are becoming more and more frequent and one question spontaneously arises: is climate change making the weather more extreme? This is one of the reasons why climate change i ...[Read More]
