<p class="MsoNormal">Dear MITgcm community, <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am wondering if anyone has diagnosed the terms in vorticity equation in MITgcm. I see that there are diagnostics for momentum budget, and I am curious if there are similar things for vorticity equation.

<p class="MsoNormal">Thank you very much. <u></u><u></u></p>
