Hi WRF-help,<br>
<br>
thank you very much for the information.<br>
I had the same problem, but I was working with 3 grids.<br>
I have just execute the WRF v3.2 and the results seem fine<br>
<br>
Regards, Marcos<br>

<pre wrap="">In V3.2, when you use auxiliary input such as this input option
(fine_input_stream = 0, 2, implies
that you are using auxiliary input stream 2), you need to set the
io_form for it to define the data format.
In this case, add io_form_auxinput2 = 2 in &time_control. In previous
versions, it was set in the registry by
default. This is a result of expanded IO capability in other areas.

Subject: more WRF 3.2 issues: delayed initialization of nests and
fine_input_stream
Hi again, WRF users. . .
I've come across another issue with WRF V3.2 that seemed to work fine
with WRF V3.1.1 and earlier. The netcdf problems I mentioned earlier
continue, but playing with optimization does seem to have an impact.
I'm hopeful that I'll find some settings that have reasonable
performance and also don't hang occasionally on netcdf output. The
new
issue seems separate.
I delay the initialization of the inner grids in the model runs I
described earlier (outer domain at 27 km, nests at 9km, 3km and 1km).
The nest initializations are delayed by 3 hours, 6 hours, and 9
hours -
times which coincide with the GFS input data. I believe I have set
input_from_file and fine_input_stream so that static data like
topography comes from the wrfinput_d0x files, and the atmospheric data
is interpolated from the parent grid. Ie:
input_from_file =
.true.,.true.,.true.,.true.,.true.,
fine_input_stream = 0, 2, 2, 2,
But when I look at the wrfout files, it looks like _all_ of the data
is
being interpolated from the parent grid, so we get no benefit of the
higher resolution topography. The high resolution topography is in
the
wrfinput_d0x files, and the time of the data appears to be correct (at
the time that the nests are supposed to initialize).
When run with V3.1.1, I see the high resolution topography in both the
input and output files, as I should.
I've also found that if I use V3.2 and initialize the nests at the
same
time as the outer domain (at the beginning), it also seems to work
fine
then. So it only seems to be a problem (for me) when I use delayed
initialization with the nests.
Any thoughts?
Thanks,
Mike
