The generation of noise over steep terrain (slopes greater than 30 degrees) at horizontal resolutions finer than 1 km is a well-known problem of terrain-following sigma-p coordinates.
See Katherine Lundquist's presentation at the WRF Workshop last year:
and an upcoming article in Monthly Weather Review:
The authors have developed an Immersed Boundary Method (IBM) for WRF that overcomes these problems to simulate flow over steep complex terrain, such as urban landscapes.
