Title : Role of Terrain in Atmospheric Model Numerics


Abstract:

Without any considering of model numerics, complex topography is widely used to represent mesoscale forcing in atmospheric research. However, in atmospheric simulation models the treatment of complex topography in the model numerics may have a significant impact on the overall solution accuracy. In this presentation, we are investigating some relationships between high-frequent topography and atmospheric model numerics. Kinetic energy spectra and air-turbulence index are examined using a real case study to evaluate high-frequent forcing, which are strongly affected by model numerics. Our views in dealing with these terrain-related issues will be discussed in the context of our experiences in the development and testing of the WRF and MPAS models.
