Overview of climate changes

Changes in snowfall

Mean daily snowfall averaged across calendar months had a difference of -0.10 mm/day compared with the earlier reference period. This is an unweighted comparison of monthly means, not a change in monthly snowfall totals. Monthly differences varied: the largest decrease was in February, with a difference of -2.92 mm/day in mean daily snowfall, while the largest increase was in December, at +2.75 mm/day. These are monthly mean differences, not descriptions of snowfall on individual days.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, had a difference of +0.32 mm/day compared with the earlier period.

By contrast, August had the largest monthly decrease, a difference of -0.07 mm/day; these monthly contrasts do not imply that rainfall moved in the same direction every month.
