Hi Soma,
It’s hard to determine exactly what the problem is without a copy of your data file to test the script myself, but I suspect there may be something odd happening with the time_axis_labels and gsn_csm_hov calls:
time_axis_labels(ts&time,res,restick)
plot = gsn_csm_hov(wks,xDay(:,:,{78}),res) ; lat vs time.
In particular, I noticed that the time dimensions on the variables ts and xDay are different sizes (248 for ts, 31 for xDay). You may want to try using xDay&time in your time_axis_labels call, although you might also need to adjust the value of restick at ttmMajorStride to account for the smaller time dimension on xDay.
If you are still having trouble generating correct Y-axis labels after trying this, would you perhaps be able to provide us with a copy of your data file? (See uploading instructions: https://www.ncl.ucar.edu/ftp_files.shtml <https://www.ncl.ucar.edu/ftp_files.shtml>)
I hope this helps,
Kevin
