Dear teacher, I am glad to receive your reply.
I put 2018 GEFS data, using ncl_filedump gec00. t00z. pgrb2a. 0p50. f000 file and gec00 t00z. pgrb2b. 0p50. f000 file content presented to you separately, and named 2018 gefs_a_file. TXT and 2018 gefs_b_file. TXT, using the data of 2018 I was completely can run through the WRF, can get wrfout file.
However, the GEFS data for 2019 should be updated. I present their contents to you in a similar way, named 2019gefs_a_file.txt and 2019gefs_b_file.txt.I used 2019 GEFS data, ungrib.exe, metgrid.exe and real.exe without any problems.However, wrf.exe will stop automatically after the end of the first integral step, and there is no error report. Attached are the relevant files and namelist, thank you for your help
