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.
