Dear Colleagues,

I am very confused about my running result. I set the history_interval as 5 min, but the wrfout is always divided into two files:
wrfout_d03_2019-06-11_00:00:00
wrfout_d03_2019-06-14_11:20:00

I also ran WRF with 10, 30 and 60 mins history_intervals, the results are normal. Could you please kindly let me know why the "5 min" outcome has such issue? Many thanks. For your convenience, I attach my namelist.wps and namelist.input.

Best regards,
Stella

Hi,
The reason this is happening is due to these settings in your namelist.input file:
Code: 
run_days                            = 3,
 run_hours                           = 23,
 history_interval                    = 5,  5,  5,
 frames_per_outfile                  = 1000, 1000, 1000,

So you're asking for output every 5 mins, and you're asking that 1000 outputs be in each output file. If you do the math, the 1000 outputs are reached after 3 days, 11 hours, and 20 mins, at which point the next file is created. If you want everything in one file, you'll need to increase frames_per_outfile.
