The tropical nature of an intense Mediterranean cyclone in the ocean-atmosphere system Open
Certain intense Mediterranean cyclones display characteristics of tropical cyclones: they have an axisymetric cloud cover with an eye-like feature visible in satellite images and some produce a cold wake evidenced by remotely sensed sea su…

Complementarity of Large-Eddy Simulation and Synthetic Aperture Radar to understanding surface winds in an extra-tropical cyclone Open
Extra-tropical cyclones are intense meteorological phenomena, highly destructive and sometimes causing fatalities. Although the mechanisms of formation and propagation are well known, a current challenge is to correctly represent in numeri…

Impact of Surface Turbulent Fluxes on the Formation of Roll Vortices in a Mediterranean Windstorm Open
Roll vortices can have a significant influence on the exchanges of momentum, sensible heat and moisture throughout the boundary layer. They have been shown to reinforce air‐sea interactions under strong wind conditions. This raises the que…

The role of wave coupling from the mesoscale to the sub mesoscale in a sting jet windstorm Open
Windstorms associated with extratropical cyclones are destructive natural hazards. Processes governing the formation of near-surface winds are crucial for their societal impact but are not well understood and too small scale to be explicit…
