Hi Matt,
I have checked the diagnosed wind stress, the wind stress pattern and value are OK.
Strangely, I can successfully run the 4-degree configuration of global_with_exf, and the currents seem OK, but when I increased the resolution to 1grid*1grid, there are little currents outside the equator (even at the time of 100 years).
Here is my data.exf and EXF_OPTIONS.h.

Hi Fei
How does your wind stress look? That is the first thing I would check.

Subject: [MITgcm-support] A question about the currents

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.
Hi everyone,
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.
Attached are the currents at the time of 40 years.
