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

Tommaso Alberti January 19, 2021

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”

Tommaso Alberti December 23, 2020

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]

Can we connect the exceptional floods in France and Italy associated with the storm Alex to climate change?

Davide Faranda October 14, 2020

The first days of October were marked by an extreme weather event: storm Alex, a cyclone of Atlantic origin, caused massive showers and thunderstorms over Provence, the Alps, Piedmont and Liguria. In these regions, numerous historical records of precipitation were broken causing the flooding of several streams and rivers in which many people lost their lives. Economic damage was also significant a ...[Read More]
