<p class="MsoNormal"><span style="font-size:11.0pt">Hi David,<br>
<br>
I think Um_Advec/ Vm_Advec, always include the Coriolis term (even if using fluxform).<br>
The first level decomposition should be:<br>
Total-U-tendency = Um_Advec + Um_Diss + Um_ImplD + Um_dPhiX + Um_Ext + AB_gU<br>
<br>
And on second level, can try to split Um_Advec. This depend on the use of <br>
flux-form or vector-inv. For the later, should be the sum of Coriolis, Bernouilli
<br>
term (no diagnostics), Um_AdvZ3 and Um_AdvRe (+ vertical/NH metric terms).<br>
but I did not checked so I might have missed one.<br>
<br>
Cheers,<br>
Jean-Michel<br>
