[Met_help] [rt.rap.ucar.edu #63606] History for Interest Value Determination

[John Halley Gotway via RT]

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

John, view in html, after reviewing the tutorials on MODE I am still not sure if area ratio is part of the interest calculation or separate.  In the attached slide, member 5 has a higher interest value but the area is way too big.  So, did the area ratio contribute to this interest score or not?  These are runs of 4km WRF ensemble members.  I attached the config file I used.

Thanks

Bob Craig

Bob,

I looked at the config file you sent and see that the "weight" config
file
option is not included in there.  Thus, MODE will be using the values
from
the default config file, found here:
METv4.1/data/config/MODEConfig_default.

Here how the weights are set in there:

//
// Fuzzy engine weights
//
weight = {
   centroid_dist    = 2.0;
   boundary_dist    = 4.0;
   convex_hull_dist = 0.0;
   angle_diff       = 1.0;
   area_ratio       = 1.0;
   int_area_ratio   = 2.0;
   complexity_ratio = 0.0;
   inten_perc_ratio = 0.0;
   inten_perc_value = 50;
}

So it looks like the area_ratio is being likely being used.

I'd suggest 2 things:

(1) Make a copy of that default MODE config file and edit it from
there.
(2) If you run MODE with a high enough verbosity level (-v option),
you
should see more detailed information about how the interest values are
being computed.

Hope that helps.

Thanks,
John
