Idealized atmosphere, real topography

[GunnarLivik]

I'm interested in running WRF with an idealized atmosphere and real topography. Does anyone know how to do this?

I would like to have the initial state of the simulation where there is no wind (small or no synoptic pressure gradients), in order to evaluate katabatic winds occuring due to radiative cooling, and therefore would like to get rid of any synoptic winds.

I hope someone has done anything similar, and could make a response.

Thanks,

Also, does anybody know of any tool that can transform topography data to model grid coordinates (i.e. plane cartesian coordinates)?

Are you planning on using the idealized mountain code for this? I would imagine you could create "real" topography in the same manner as the code for the bell shaped mountain. Extract a profile of terrain height and fit a function to it that you can code in.

No wind is tricky ... you will have to use the 6th order diffusion, I am guessing.

good luck.

I'm not sure if I'm going to use the idealized mountain code. Is there a possibility to get something like the grav2d in 3D?

By real topography I mean the real terrain of an area in f.ex Norway, just to be clear.
