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

• break-up of scale invariance
• effects of buoyancy

• horizontal boundary conditions
• surface heterogeneity and vegetated surfaces
• complex topography (if time permits)

• flow over forests and crops
• dispersion of pollutants and biological particles
• cloud dynamics
• Future directions
