Research interests:

Atmospheric dynamics:

  • The life cycle of midlatitude and Arctic cyclones.
  • Midlatitude high-impact weather events: wind storms, heavy precipitation events, cold spells.
  • Rossby waves: excitation, propagation and breaking.
  • Low-frequency atmospheric variability: North Atlantic Oscillation, weather regimes (e.g., blockings), annular modes.
  • Mid-latitude air-sea interactions.

Predictability of atmospheric flow:

  • Initial error growth
  • Model error growth: sensitivity to deep convection and cloud microphysics representation in numerical models

Geophysical Fluid Dynamics:

  • Shear instabilities: barotropic, baroclinic.
  • Wave-mean flow interactions.
