Climate Change Chart of Taoyuan, Taiwan

Overview of climate changes

Temperature changes

Monthly mean temperature shows a difference of +0.81 °C averaged across calendar months; 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 July, with a difference of +1.54 °C. These figures describe differences between reference-period averages, not a continuous change or a uniform shift in every month.

Changes in rainfall

Mean daily rainfall has a difference of +1.89 mm/day averaged across calendar months, using an unweighted mean of monthly values rather than monthly totals or a day-weighted annual average. The largest monthly increase was in May, with a difference of +3.77 mm/day. The overall mean difference does not imply that rainfall increased in every month, and the daily-mean measure should not be read as a change in monthly accumulation.

Changes in sunshine duration

Mean daily sunshine duration was lower by a difference of -0.66 hours/day averaged across calendar months, based on an unweighted comparison of monthly means. The largest monthly decrease was in December, with a difference of -1.65 hours/day. By contrast, the largest monthly increase was in July, with a difference of +0.18 hours/day. This contrast shows why the mean describes an aggregate rather than the direction of change in each month.

Changes in snowfall

Mean daily snowfall had a difference of 0.00 mm/day averaged across calendar months at the displayed precision; that rounded result does not establish that snowfall was absent or unchanged at finer precision. The largest monthly increase was in January, with a difference of +0.03 mm/day. These are daily means, not monthly snowfall totals.
