DOI: 10.1002/qj.3086
Abstract: The projected changes in temperature due to global warming will have a profound effect on the behavior of midlatitude eddies. Using an idealized moist global circulation model, the atmospheric barotropic energy balance is studied over… read more here.

Changes in mean flow and atmospheric wave activity in the North Atlantic sector
Sign Up to like & getrecommendations! Published in 2019 at "Quarterly Journal of the Royal Meteorological Society"
DOI: 10.1002/qj.3660
Abstract: In recent years, the midlatitudes are characterized by more intense heatwaves in summer and sometimes severe cold spells in winter that might emanate from changes in atmospheric circulation, including synoptic‐scale and planetary wave activity in… read more here.

DOI: 10.1002/qj.3821
Abstract: The Holton–Lindzen–Plumb (HLP) model describes the spontaneous emergence of mean flow reversals in stratified fluids. It has played a central role in understanding the Quasi‐Biennial Oscillation of equatorial winds in Earth's stratosphere and has arguably… read more here.

DOI: 10.1016/j.ast.2018.06.005
Abstract: Abstract The mean flow compressibility effects greatly influence the behavior of turbulent flows, as long as the flow is compressible. The fact is even though Favre average has taken into account the variation of the… read more here.

DOI: 10.1016/j.ocemod.2019.01.007
Abstract: Abstract Turbulence in the ocean dominates the vertical movement of heat and salt, as well as chemical and biological particulates. The modelling of turbulence is therefore essential to forecast the strength of the biological pump,… read more here.

DOI: 10.1017/jfm.2020.109
Abstract: We tackle the question of how anisotropy in flows subject to background rotation favours structures elongated along the rotation axis, especially in turbulent flows. A new, wave-free mechanism is identified that challenges the current understanding… read more here.
