Was everything else the same? Same number of processors? Same exact

Hi,</span></p>
<p class="MsoNormal"><span style=
"font-size:10.0pt;font-family:&quot;Arial&quot;,&quot;sans-serif&quot;">
&nbsp;</span></p>
<p class="MsoNormal"><span style=
"font-size:10.0pt;font-family:&quot;Arial&quot;,&quot;sans-serif&quot;">
I was surprised to find that running on WRF 3.4 the same domain,
with the same initial and boundary conditions could get different
results.</span></p>
<p class="MsoNormal"><span style=
"font-size:10.0pt;font-family:&quot;Arial&quot;,&quot;sans-serif&quot;">
&nbsp;</span></p>
<p class="MsoNormal"><span style=
"font-size:10.0pt;font-family:&quot;Arial&quot;,&quot;sans-serif&quot;">
I’ve read about the fact that the internal variability of a model
can give different results, for the same period of simulation, when
the initial conditions change even just for a few
days/hours.</span></p>
<p class="MsoNormal"><span style=
"font-size:10.0pt;font-family:&quot;Arial&quot;,&quot;sans-serif&quot;">
However, running 2 times the same and finding differences till +/-
8m/s in U10 for example is scaring. Anyone can explain me how this
is possible?</span></p>
