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]

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]

NP Interview: Federico Grazzini on Climate Change casts shadows on the present and the future of the Mediterranean Basin
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. Fe ...[Read More]

NP Interviews: Davide Faranda (CNRS) on the topic “global warming and extreme events in Europe”

Davide Faranda is a physicist at the French National Center for Scientific Research (CNRS). His main interests are devoted to the construction of a statistical mechanical and dynamical systems framework for the study of atmospheric motions. In particular, his works aim at the characterization of the metastable states of the atmospheric circulation with simple mathematical and statistical tools, an ...[Read More]
