Yes.

Climatological stats can be described for the annual cycle. The
climatological monthly mean temperature would be "time: mean within years
time: mean over years", and you would use the climatological time bounds to
indicate the start and end of months (or other portions of the annual cycle).
This would produce twelve climatological monthly values (for each location).
Do you mean you then apply a third operation to compute the range of these
twelve values?
