Climate Change Chart of Nizhny Novgorod, Russian Federation

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +2.26 °C compared with the earlier reference period. This is an unweighted average of the monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase in mean temperature occurred in January, with a difference of +5.50 °C. This identifies the strongest increase among the monthly means, rather than describing every month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of +0.11 mm/day compared with the earlier reference period. This is an unweighted average of monthly means for daily rainfall, not a change in monthly rainfall totals. The largest monthly increase in mean daily rainfall was in November, at a difference of +0.47 mm/day. By contrast, August had the largest monthly decrease, with a difference of -0.69 mm/day; these extrema show that monthly changes were not uniform.

Changes in snowfall

Averaged across calendar months, mean daily snowfall had a difference of +0.59 mm/day compared with the earlier reference period. This is an unweighted average of monthly means, not a monthly total, and describes an aggregate rather than a uniform change throughout the year. The largest monthly increase in mean daily snowfall was in January, with a difference of +4.30 mm/day. In March, the largest monthly decrease was -2.16 mm/day, underscoring the contrast between the monthly extrema without implying that snowfall was absent in either period.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of -0.06 hours/day, indicating a small overall decrease at the precision shown. This unweighted mean of monthly averages does not imply the same change in every month. The largest monthly increase in mean daily sunshine duration occurred in March, with a difference of +0.93 hours/day. The largest decrease was in January, at a difference of -1.13 hours/day, showing opposing monthly changes behind the near-level average.
