2010 Tutorial School on Fluid Dynamics: Topics in Turbulence


LES Applications in Meteorology

Marcelo Chamecki, Pennsylvania State University

Outline:  

The atmospheric boundary layer (ABL)
Wall models and buoyancy effects
Subgrid scale models for ABL flows:

  • break-up of scale invariance
  • effects of buoyancy
Technical challenges
  • horizontal boundary conditions
  • surface heterogeneity and vegetated surfaces
  • complex topography (if time permits)
Example of applications: (as time permits)
  • flow over forests and crops
  • dispersion of pollutants and biological particles
  • cloud dynamics
  • Future directions
