If you are using the newer versions of the model, rhmin and rhmax are set in param.F, and read as:

rhmax    = 1.01    ! RH at which FCC = 1.0
rh0oce   = 0.90    ! Relative humidity threshold for ocean
rh0land = 0.80    ! Relative humidity threshold for land

In older versions they sit in regcm.in. For more information on SUBEX, read this article:

Dear all,
I use the RegCM3 datas to

simulate ouest african precipitations, the results show that large scale precipitation

are surestimated by a factor 3 compared to the CRU observations, I

want to know the values of RHmin and RHmax in SUBEX scheme,

these values will help me to discuss these results.

Thanck in advance.
