Hi Fei,
<div class=""><br class="">
</div>
<div class="">
<div class="">
<div>This sounds like there is an error in the routine you use to convert the 4 degree forcing into 1 degree forcing. Have you double checked that the forcing fields for the 1 degree simulation are correct?</div>
<div><br class="">
</div>
<div>As an aside, that EXF_OPTIONS.h file you copied into the email suggests you are using an old version of the model from 2015. You should probably update the code to the latest version.</div>
<div><br class="">
</div>
<div>Cheers,</div>
<div>Ed</div>

I'm really sorry for the disturbance. I found the text of my previous email consisted of error codes, maybe it is related to my email. So I use another email to resend the question. Thank you so much.<br class="">

Hi everyone,<br class="">
<br class="">
Recently, I ran a global ocean model configuration which is similar with the global_with_exf but with 1 grid*1 grid resolution. Strangely, I found the currents were mainly located on the equator (e.g., strong westward currents over eastern equatorial Pacific),
and there are no western boundary currents and ACC.<br class="">
<br class="">
Attached are the currents at the time of 40 years.<br class="">
