在MM5模块下,怎样修改物理过程如:边界层方案、积云对流化参数等,程序本身自带的是:
# 6. Physics Options
# The first MAXNES values in the list will be used for the corresponding
# model nests; the rest in the list can be used to compile other options.
# The exception is FRAD, of which only the first value is used in the model,
# (i.e., only one radiation option is used for all nests). The rest allow
# other options to be compiled.
# Compilation of Arakawa-Schubert cumulus scheme requires imsl.

我修改成这样就不行:
