Modify coriolis parameter for sloped surface cases #42

Closed cbegeman closed 5 years ago

cbegeman commented 5 years ago

When a surface slope is used (alpha_surface in degrees), the whole computational domain is rotated. In PR https://github.com/xylar/palm_les_lanl/pull/4, the gravity vector was rotated accordingly. In this PR, the coriolis parameters are also rotated. Stokes drift forces are not modified and are thus inaccurate for sloped domain cases.

@xylar It'd be great to have you look over this PR. The modifications to coriolis terms are small for the slopes we're looking at. If you want to test this, you can use the same namelist files for the constant flux layer cases but set alpha_surface equal to a nonzero slope in degrees.
