No sign of storm track in runs with `OFCL` (faked as `BEST`) track

Question

No sign of storm track in runs with `OFCL` (faked as `BEST`) track

Here are the comparison of SCHISM outputs (out_2d_1.nc) for BEST and fake OFCL tracks of hurricane florence!
Looks like the OFCL track run does not have storm track.

Update on the PaHM models with faked BEST track run!
@pvelissariou1 and @SorooshMani-NOAA, Here are outputs of SCHISM run with faked BEST track and two model_type_pahm values (1: Holland, and 10: GAHM)

As you see, both did not simulate wind (zero wind speed for the entire domain)!

@fariborz Daneshvar - NOAA Affiliate ***@***.***> Fariborz did you by any chance run your track file through PaHM standalone? If yes, did you plot the results from PaHM? When I used your track file in PaHM I actually saw wind speeds that are not zero (> 1.0 m/s). Keep in mind that, if the hurricane (eye) is not in the domain or near the domain the wind fields (speed) will be zero. I don't know what time frame you plotted and you have zero winds (maybe the storm has not reached the domain yet) but see if you have this issue at later times when the storm has approached the domain.

@pvelissariou1 I think there might be some different between the two code. You ran the track through PaHM standalone a couple of days ago and it worked, but using SCHISM it doesn't seem to work. We're using SCHISM commit ddf1564

Answer 4 · 2023-08-09T12:24:37.000Z

If I remember correctly, the PaHM core code in SCHISM is exactly the same as in PaHM standalone. I have checked that a couple of times. Later today I will check again and also the commits. I have run PaHM+ADCIRC, PaHM+ADCIRC+WW3 in CoastalApp-testsuite without noticing any issues. Let me check though and I'll let you guys know about my findings. Panagiotis Velissariou, Ph.D., P.E.

I understand, that's why it's strange. Also please let us know if it helps if we debug it. In that case what are the flags we need to set to get the debug symbols, and how would we have to start SCHISM to debug?

Answer 6 · 2023-08-09T15:55:56.000Z

@pvelissariou1 Yes, I ran PaHM standalone for the faked BEST track (see plots for max wind speeds here: noaa-ocs-modeling/PaHM#27 (comment))

As @SorooshMani-NOAA mentioned, it might be a difference in two codes?!
