The Mediterranean region stands as a poignant testament to the far-reaching impacts of climate change. From extreme weather events to rising sea levels and increased pollution, the consequences of global warming are acutely felt. In this climate change hotspot, the interconnection of risks creates a complex web that affects ecosystems, economic activities, and human health. Recognizing the need fo ...[Read More]

NP Interview: Federico Grazzini on Climate Change casts shadows on the present and the future of the Mediterranean Basin

Davide Faranda November 17, 2022

Monthly mean sea surface temperature averaged over western and central Mediterranean sea [0E - 22E], months April - November. The blue line corresponds to the recent climatology 1991-2020 with the shading respectively showing 1,2,3 standard deviations of the monthly averages from the mean. Symbols are showing this year values and, for comparison with a previous strongest marine heat wave, the values recorded in 2003.

Weather extreme events in the year 2022 are really hitting the Mediterranean basin very hard. Since the beginning of the year we are observing a widespread drought, heatwaves but also severe thunderstorms. Few days before the COP meeting in Sharm-el-sheik we discussed one of the experts of Mediterranean climate, Federico Grazzini, to unveil whether these events can be linked to climate change.

How climate change can possibly increase the intensity of tornadoes in Europe

Davide Faranda October 26, 2022

On October 23 2022, a tornado outbreak occurred in France, causing extensive damages. Tornadoes in France are a relatively rare phenomenon, even more so in the second half of October. This weather phenomenon is linked to intense thunderstorms, and it is difficult to predict because it is very localized. Will global warming make this weather more frequent or intense? A thundercloud that grows visib ...[Read More]

NPG Paper of the Month: “Application of a local attractor dimension to reduced space strongly coupled data assimilation for chaotic multiscale systems”

Tommaso Alberti April 23, 2020

Local dynamical properties of a segment of an example run for the coupled Lorenz system. (a) Alignment of directions of error growth plotted along the x coordinate of the ocean subsystem. Large orange stars indicate high alignment of error growth in the unstable or neutral subspaces. (b) Finite-time Lyapunov exponents (FTLEs) computed over window τ = 4. (c) Local Kaplan-Yorke dimension calculated from FTLEs.
