Research interests

Ocean and atmosphere dynamics at the air-sea interface

  • Coupled interactions at mesoscale
  • Air-sea interactions in tropical cyclones

Regional coupled modeling: WRF-ROMS/CROCO-NEMO-WW3

Ongoing projects

  • PULSATION (Peta scale mULti-gridS ocean-ATmosphere coupled simulatIONs) :
    • Impact of small-scales phenomena on systematic bias in climate models
    • Quantifying small-scale processes that determine large-scale climate
    • Multi-scale coupled ocean-atmosphere simulations on petascale computer
  • CROCO (Coastal and Regional Ocean COmmunity model) :
    • Research on numerical developments and methods for small-scale ocean modeling in coastal restions and related multidisplinary questions
    • Sharing research and developments in a common modeling tool build to assess realistic and complex systems
  • CTroVagueS (Interactions Tropical Cyclones-Waves-Submersion)
    • Characterize wind-wave-current interactions in tropical cyclones
    • Evaluate wave setup, runup and surge due to cyclones
