Climate Change Chart of Mandalay, Myanmar

Overview of climate changes

Temperature changes

Monthly mean temperature averaged across calendar months shows a difference of +1.18 °C compared with the earlier reference period; this is an unweighted average of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in December, with a difference of +1.82 °C. This identifies the strongest increase among the monthly means, rather than implying that every month warmed by the same amount.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of +0.32 mm/day in the more recent period. This unweighted average of monthly means describes daily amounts, not monthly rainfall totals, and does not mean that rainfall increased in every month. The largest monthly increase in mean daily rainfall occurred in July, with a difference of +1.53 mm/day. By contrast, December had the largest monthly decrease, a difference of -0.52 mm/day; these extrema show that monthly changes did not all move in the same direction.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of +0.27 hours/day compared with the earlier reference period. This is an unweighted average of monthly means, rather than a day-weighted annual figure, and it does not describe the change in every individual month. The largest monthly increase in mean daily sunshine was in July, with a difference of +0.80 hours/day. In April, sunshine instead recorded the largest monthly decrease, a difference of -0.36 hours/day, showing that the overall mean increase coexisted with a monthly decline.
