i am a student from China. Recently, i compare the runoff simulated by RegCM4.1.1 coupled with BATS and CLM over China. The monthly mean runoff simulated by RegCM_BATS vary from -8 to 60, but that simulated by RegCM_CLM vary from 0 to 110000, all the settings are the same except coupling BATS or CLM, does anyone else have met this problem? How can i solve it?
