<p>Hi Jody,</p>
<p><br>
</p>
<p>Thanks for your quick reply.</p>

<p>I did set my density field to satisfy the thermal wind. When MITgcm solves the Navier Stokes equation, does it scale the density in any way? This may change my thermal wind relation.</p>

<div>You need to set the density field to satisfy the thermal wind as well.

<p>Hi,</p>
<p><br>
</p>
<p>I have a question regarding setting up a geostrophic current in ocean modeling.</p>
<p><br>
</p>
<p>I have initialized a geostrophic current V(x,z) through vVelInitFile in data. The initialization seems working fine, but since for the geostrophic current to exist, I need to have rotation (see thermal wind relation). However, since the rotation is on, the
current will be changed after the initialization. I would like to have an unchanging current V(x,z), which does not depend on time. </p>
<p>How do you suggest I do this?</p>
<p><br>
</p>
<p>Thanks a lot</p>
