Yes. > But how about common continentality indices based on the annual range of > monthly mean temperatures? > Is there a "within months" such that the cell method for the basic element of > the continentality index would be "time: mean within months time: range > within years" ? Or is there another solution? 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?
