 Simulations with topography require the application of MOST between each surface and the first computational grid point outside of the topography. 
 For vertical and horizontal downward-facing surfaces, neutral stratification is assumed for MOST. 
-The topography implementation has been validated by [#letzel2008 Letzel et al. (2008)] and [#kanda2013 Kanda et al. (2013)}.

 [#park2013 Park and Baik (2013)] have recently extended the vertical wall boundary conditions for non-neutral
 stratifications and validated their results against wind tunnel data. Up to now, however, these modifications are not included in PALM 4.0. Figure 4 shows exemplarily the development of turbulence structures induced by a densely built-up artificial island off the coast of Macau, China (see also animation in [#knoop2014 Knoop et al., 2014]). The approaching flow above the sea exhibits relatively weak turbulence due to the smooth water surface. Within the building areas, strong turbulence is generated by additional wind shear (due to the walls of isolated buildings) and due to a general increase in surface roughness.
