Climate Change Chart of Nagpur, India

Overview of climate changes

Changes in rainfall

Mean daily rainfall, rather than monthly rainfall totals, averaged across calendar months shows a difference of -0.56 mm/day in the more recent period. This unweighted mean summarizes the month-by-month averages and does not indicate that rainfall shifted uniformly in every month. The largest monthly decrease occurred in July, at a difference of -4.57 mm/day in mean daily rainfall. In August, the largest monthly increase was a difference of +1.31 mm/day; these contrasting monthly changes show why the overall mean should not be read as a description of each month.

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.71 °C compared with the earlier reference period; this is an unweighted average of the monthly means, not a day-weighted annual figure or a measure of daytime maximum temperatures. The largest monthly increase was in November, with a difference of +1.60 °C. By contrast, January recorded the largest monthly decrease, a difference of -0.19 °C. These extrema describe monthly means and do not imply that every month changed in the same direction.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of +0.07 hours/day compared with the earlier reference period. This unweighted summary of monthly means is not a day-weighted annual average, and it does not establish the direction of change in every month. The largest monthly increase in mean daily sunshine was in July, with a difference of +0.63 hours/day. The largest monthly decrease was in March, at a difference of -0.19 hours/day, so the overall mean difference should be understood alongside these month-specific contrasts.
