<p>Dear Jeremy, <br>
</p>
<p>the ordering of the temperature values is from the surface of the
ocean downward. So, did you prescribe such a strong increase of T
with depth (it sounds as if you did that)? Then you will
inevitably create an unstably stratified water column. In reality
you would get a very strong vertical overturning over the whole
water column. How the model handles that depends on whether you
use hydrostatic and non-hydrostatic code, but I am not surprised
that that kills the solution. Rather than searching for where the
model blows up, I would in this case choose a more realistic
initial condition. <br>
</p>
<p>Cheers, Christoph<br>

<div>Dear MITgcm forum,</div>

</div>
<div>Hope all are well. A question about changing tRef in "data"
in the internal wave verification.</div>
<div>When changing tRef from the default to a linear slope, say
from 5 to 20 in increments of 0.5, I get the following error:</div>
<div><br>
</div>
SOLUTION IS HEADING OUT OF BOUNDS: tMin,tMax= -1.994E+24
1.124E+24<br>
exceeds allowed range (monSolutionMaxRange= 1.000E+03)<br>
MON_SOLUTION: STOPPING CALCULATION at Iter= 20<br>
S/R ALL_PROC_DIE: ending the run<br>
STOP ABNORMAL END: S/R MON_SOLUTION, stops due to EXTREME
Pot.Temp<br>
<div><br>
</div>
<div>I think there is a relationship between the time
discretization and tRef for numerical stability, but I don't
know what it is.</div>
<div>Best</div>
