about SKEBS parameters in WRFV3.9

[summer2021]

Hi，
In module_stoch.F, why to Initialize streamfunction with grid%KMINFORCT,grid%KMAXFORCT, grid%LMINFORCT and grid%LMAXFORCT of potential temperature, but not grid%KMAXFORC, grid%LMINFORC and grid%LMAXFORC of streamfunction.

Thank you!



! Initialize SKEBS
! Initialize streamfunction (1)
if ((.not.config_flags%restart) .or. (.not.config_flags%hrrr_cycling)) then
call rand_seed (config_flags, grid%ISEED_SKEBS, grid%iseedarr_skebs , kms, kme)
endif
