<p>
<span style="font-family:Georgia;font-size:16px;">But I want to know the mean latitude at each longitude point separately. If I use dim_avg_n_wrap, I cannot plot the latitude, longitude plot like in the attachment</span><span style="font-family:Georgia;font-size:16px;">. </span>

<span style="font-family:Georgia;font-size:16px;">Thank you so much again and best regards,</span>

<span style="font-family:Georgia;font-size:18px;">I have the barotropic streamfunction values in the southern ocean (attached figure). I want to get the mean latitude (ACC core) at each longitude. And plot the data as Latitude longitude contour plot using one contour line. I am bit lost about how can I do this. It would be great if you can give me some ideas about getting the mean Latitudes for each and every longitude.</span>
