Hello every RegCM3 users,
Now I am using RegCM3 to simulate regional climate. I chosen the 1990 year, in the simulation, ds = 10, clat = 48.5, clon = 117, iy = 90, jx = 100, DATTYP = EH5OM, SSTTYP = EH5RF. In this situations, I could run the RegCM3 successfully.
When I chosen the 2020 year, the simulation parameters as follow: ds = 10, clat = 48.5, clon = 117, iy = 90, jx = 100, DATTYP = EH5OM, SSTTYP = EHA1B. and other parameters were the same with the simulation in 1990. terrain.x and icbc.x could run successfully, but when the regcm.x run, it was found that “floating point exception”. Who can tell me the reasons? Best regards.
Part of information when the regcm.x run.
