I ran the offline CICE model .
I did a test : change the Great lakes to ocean and modify related files.
But after I ran the CICE offline model , the ice thickness is all euqal to 0 in the Great lakes.
I checked the sea surface temperature I modified in POP file and there exsits lower temperature than 0 in some months.
But why the results have no ice ?
Waiting for somebody helping me ! Thanks !
