Spontaneous Imbalance Workshop #1:
Perspectives from atmospheric and oceanic dynamics
Pilot Study to assess the current understanding of lateral mixing in the ocean
I am interested in the regime of oceanic motions that are influenced by both the Earth's rotation and buoyancy forces. This is the regime for which the Rossby number, Ro, is O(1). This regime is dynamically important because it links the energy-carrying, large scales (Ro<<1 regime) to the small, isotropic scales (Ro>>1 regime) at which energy is dissipated. Motions in this regime include inertia-gravity waves, submesoscale coherent vortices (SCVs) (sometimes referred to as vortical modes) and rotating, stratified turbulence. Understanding the dynamical processes that govern energy transfer between the different regimes remains the primary focus of my research.

I am currently involved in 4 research projects:
  1. Lateral dispersion due to vortical-mode stirring (co-PI: Miles Sundermeyer, University of Massachusetts, Dartmouth; funded by the National Science Foundation)

  2. Generation of inertia-gravity waves following the instability of large-scale flows (co-PI: Tim Dunkerton, NorthWest Research Associates; funded by the National Science Foundation)

  3. Internal Tide Generation over Steep Topography (PI: Eric Kunze, University of Victoria, BC Canada; funded by the Office of Naval Research)

  4. Wavebreaking of inertia-gravity waves revisited (with Pascale Bouruet-Aubertot, LODYC, Paris France)
