Sensitivity test for the WRF

[edwardsjethro]

Dear WRF community,

I am doing a sensitivity test of my WRF case. Before that, I want to ask will identical simulation produce different result.

If not, how large will the deviation be? e.g., the deviation in 2m air temperature.

Really appreciate if you could give some comments. Thanks.

If you don't change anything - i.e., you use the same compiled WRF, same namelist, same domain, dates, physics, etc. then two identical runs should produce the exact same results.
