Dear WRF&MPAS experts,
I would like to use WRF to do several sensitivity tests on water vapor, such as modifying the water vapor content of a certain area, and now I have two questions:
1. What files and variables should be modified for the water vapor test? The RH in met_em* files or the QVAPOR in wrfbyd and wrfinput? or both is ok? (As met_em files would be used to regenerate the initial boundary field)
2. Is it appropriate to modify the water vapor variables in this way. For soil moisture and SST, which are assumed to be independent external forcing for atmosphere. I think it is fine to modify a single variable, but for non-independent processes inside the atmosphere, is it necessary to modify variables such as temperature and pressure to match the change in water vapor. Or is it okay to modify only the water vapor, as long as the spin-up time is long enough to make the system adaptively stable?
Thanks for you help!
