A term for the smoothing process used by J. C. Bloxam (1860). He described it as follows: “The method is founded on the fact that, in meteorology, the mean of 10 or 11 consecutive days gives more correctly the normal constant value for the middle day of the series, than the middle day itself gives; and then the value for every day in the year having been calculated upon this principle, the whole series of amended values can in turn be subjected to the same process; and this process may be reiterated until the daily values are brought to sufficiently regular ascending and descending lines. ” See consecutive mean.
