Research Interests / activity: Atmospheric stability modeling. Theory and representation of buoyancy effects in Rapid-Distortion Theory (RDT), Large-eddy simulation (LES), Reynolds-Average Navier-Stokes (RANS), and mesoscale models; profile theory beyond the surface-layer; second-moment statisticalrelations for ABL fields. Atmospheric turbulence/subgrid modelling. Representation of atmospheric turbulence and its multi-scale interaction with terrain, via LES, RANS, RDT, and quasi-linearized flow models. Scale-dependent terrain characterization.  Terrain-induced drag; spectral and statistical representations; effective roughness; scale/resolution-dependent roughness. Mesoscale-microscale interaction. Adapting mesoscale output to drive linear and nonlinear (LES/RANS) microscale models; mesoscale and microscale sub-grid parameterization of turbulent fluxes. Probabilistic meteorological characterization.  Statistical representation of observed and sampled fields and reduced normalized representations, for generalizable application in e.g. wind energy. Air-sea interaction and marine boundary layer.  Effect of ocean waves on turbulent atmospheric fluxes; modeling it in microscale (e.g. large-eddy simulation [LES]) and mesoscale codes.  Phase change and sea spray. Long-range noise propagation from wind turbines. Stability and terrain effects on propagation of turbine noise.
