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]

Iota, this is the name of the last category 5 hurricane in the Atlantic Ocean. Iota is a non-name because normally hurricanes are named by NOAA starting from A to Z but when the alphabet is over, they are just identified from a letter of the Greek alphabet. Iota is a special cyclone not just because its name implies that the hurricane season is particularly rich in storms but also because of its e ...[Read More]

Perspectives on Climate Science: from historical developments to research frontiers

Tommaso Alberti October 5, 2020

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]

NPG Paper of the Month: “Simulation-based comparison of multivariate ensemble post-processing methods”

Tommaso Alberti September 29, 2020

Exemplary results for three variants of one of the simulation settings. Boxplots show comparisons to the standard ECC approach, with positive values indicating improvements in performance, measured in terms of two multivariate evaluation functions. The horizontal gray stripe indicates a region where differences in performance are not statistically significant with respect to the Diebold-Mariano (DM) test.

The June 2020 NPG Paper of the Month award goes to Sebastian Lerch and colleagues for their paper “Simulation-based comparison of multivariate ensemble post-processing methods” (https://doi.org/10.5194/npg-27-349-2020). Sebastian Lerch is a researcher at the Faculty of Mathematics of the Karlsruhe Institute Technology (KIT). He has a background in mathematics and statistics, his resear ...[Read More]
