[MITgcm-devel] exf_inscal_u/vwind

[Martin Losch]

Hi Jean-Michel,

I observed something unexpected during debugging my llc90-configuration. I want to run the model with (geographically) zonal wind only (exf/uwindfile with interpolation and rotation to the grid). When I set vwindfile = ‘ ‘, the model complains in exf_check that it need two components, OK. Then I tried exf_inscal_vwind = 0, because I thought that this would scale the “in-field” and that I then would end up with the zonal wind distributed between uwind and vwind appropriately on the faces. But in fact exf_inscal_u/vwind scale the model field uwind and vwind, so that I end up with no vwind and a mix of zonal and meridional wind on “uwind”, as usual.

Is this the intended behavior? The only way I see to run with only zonal wind is to have meridional wind file containing only zeros.
