Climate Change Chart of Guilin, China

Overview of climate changes

Changes in rainfall

Mean daily rainfall, rather than monthly totals, had an unweighted across-calendar-month difference of +1.35 mm/day compared with the earlier reference period. The largest monthly increase was in March, with a difference of +3.75 mm/day, while August had the largest decrease, at -1.16 mm/day. The overall mean difference describes the aggregate across months, not a uniform change in every month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months differed by -0.10 hours/day from the earlier reference period; this is an unweighted comparison of monthly means. The largest monthly increase occurred in August, at +0.81 hours/day, whereas the largest decrease was in November, at -1.56 hours/day. These month-specific differences add context to the mean, which does not imply the same direction of change in every month.

Temperature changes

Averaged across calendar months, the difference in monthly mean temperature was -0.16 °C; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in August, at +1.24 °C, while the largest decrease was in January, at -1.54 °C. These monthly contrasts show that the overall mean difference does not describe every month's direction.

Changes in snowfall

The unweighted difference in mean daily snowfall, averaged across calendar months, was 0.00 mm/day at the displayed precision. This unchanged rounded mean does not establish that snowfall was absent or that every month was unchanged. The largest monthly increase was in December, at +0.01 mm/day, and the largest decrease was in February, at -0.04 mm/day; these are daily means, not monthly totals.
