Climate Change Chart of Corsica, France

Overview of climate changes

Temperature changes

Across calendar months, monthly mean temperature shows a difference of +0.97 °C in the more recent period; this is an unweighted mean of monthly averages, not a day-weighted annual average or a measure of daytime highs. The largest monthly increase was in December, with a difference of +1.99 °C compared with the earlier reference period. This identifies the strongest increase among the supplied monthly temperature differences, not a change shared by every month.

Changes in snowfall

Across calendar months, mean daily snowfall has a difference of -0.34 mm/day in the more recent period. This is an unweighted mean of monthly averages, not a day-weighted annual snowfall amount or a monthly total. The largest monthly decrease was recorded in December, with a difference of -1.82 mm/day compared with the earlier reference period. This describes the monthly mean difference and does not imply that snowfall changed by the same amount in every month.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, has a difference of -0.24 hours/day compared with the earlier reference period. This is an unweighted comparison of monthly means, rather than a day-weighted annual measure. The largest monthly decrease was in November, with a difference of -0.50 hours/day. The largest increase occurred in January, at a difference of +0.12 hours/day, so the aggregate mean difference should not be read as the direction of change in each month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall has a difference of +0.19 mm/day in the more recent period. This unweighted mean of monthly means describes an overall comparison, not a day-weighted annual average or monthly rainfall totals. The largest monthly increase in mean daily rainfall occurred in March, at a difference of +0.68 mm/day. In contrast, October had the largest monthly decrease, with a difference of -0.40 mm/day; these distinct monthly changes show why the across-month mean does not describe every month.
