How to Replace default Y-axis labels and tickmarks ?

I am trying to modify the Y-axis label and tickmarks from the default
for a Hovmuller style plot, but cannot find a way to get it to replace
the default label and tickmarks with my chosen explicit values. I can
either eliminate the Y label and tick marks completely, or have both
labels appear together. Also, if tick marks are not completely
eliminated, both sets of tickmarks are present and the core is dumped.
I have tried using both gsn_csm_hov and gsn_csm_contour, but the
default Y-axis values seem to be forced in both cases.

Does anyone know how I can replace the default Y-axis label and
tickmarks ?.

I enclose the part of the script which creates the plot below, and
below that I enclose summaries of the variables which are used.

Thanks,
Helen.
