I’m researcher in physics at the French National Center for Scientific Research (CNRS). My main interests are devoted to the construction of a statistical mechanical and dynamical systems framework for the study of atmospheric motions. In particular, my works aim at the characterization of the metastable states of the atmospheric circulation with simple mathematical and statistical tools, and the characterization of rare atmospheric events, such as storms, heatwaves and cold spells. In my research, I collaborate both with mathematicians and physicists working on the characterization of highly turbulent flows, adapting the techniques used in that field to climate science.

Medicanes, thunderstorms and Acqua Alta in Venice: what is the role of climate change?

Medicanes, thunderstorms and Acqua Alta in Venice: what is the role of climate change?

A Mediterranean cyclone, high tides and climate change: these three ingredients made the 12/11/2019 acqua alta event in Venice exceptional. This combination of causes determined what climate scientists define as a compound extreme event, a non-linear mix of factors which led to several and connected extreme weather phenomena in the Mediterranean area. Let us start by the analysis of the atmospheri ...[Read More]

After Lorenzo and Ophelia, should we prepare European coasts for tropical storms and hurricanes?

After Lorenzo and Ophelia, should we prepare European coasts for tropical storms and hurricanes?

Autumn is hurricane season in the north tropics and indeed 2019 does not make exception from this point of view. After Dorian hitting Bahamas and North Carolina, the American National Hurricane Center named Lorenzo a tropical depression originating near Capo Verde. On September 25th Lorenzo became a category 1 hurricane, according to the Saffir-Simpson scale. This scale categorizes the hurricanes ...[Read More]

Abrupt Warming could bring our planet a “Hothouse Earth” with catastrophic consequences for our economy and society

Abrupt Warming could bring our planet a “Hothouse Earth” with catastrophic consequences for our economy and society

Most of us have enjoyed swings in childhood. Some have even tried to swing faster and make a full 360 degrees’ loop. Those who succeeded had a very strange feeling of not being able to predict whether, increasing the energy of the swing, the transition from normal oscillations and 360 loops would happen. Indeed, there is an energy threshold such that the swing goes from oscillations to full loops ...[Read More]

June Heatwave 2019: can we attribute the event to anthropogenic emission?

June Heatwave 2019: can we attribute the event to anthropogenic emission?

If August Rodin had lived nowadays, he would have placed his gates of hell (la Porte de l’Enfer) in Gallargues-le-Montueux, where the absolute French temperature record (45.9 °C) was set on June 28th this year. The last week of June has been very hot, not only in the south of France, but overall central Europe: in the Alps, some locations such as Chamonix (France) and Aosta (Italy) experienced tem ...[Read More]
