Bernard Legras

Bernard Legras is a Research Professor at the Laboratoire de Météorologie Dynamique of Ecole Normale Supérieure. He has held the position of Directeur de Recherche at CNRS since 1988 and was elected to Academia Europaea in 2006.

• Research Focus: Geophysical fluid dynamics, atmospheric composition, climate processes, transport and mixing in the atmosphere, tropical convection, and impacts of volcanic/wildfire plumes.

Scientific Achievements:

• 1995 CNRS Silver Medal for contributions to atmospheric dynamics.
• Identified mechanisms of convective air confinement in the Asian monsoon anticyclone using ERA5 and ERA-Interim reanalyses.
• Developed Lagrangian models (TRACZILLA) to study stratospheric transport processes.

Recent Work: His 2020 study on smoke vortices and Asian monsoon dynamics revealed upward spiral motions and exponential dilution patterns in the tropical tropopause layer. He actively collaborates on EU-funded StratoClim campaigns and offers postdoctoral opportunities in stratospheric aerosol vortex dynamics.
