Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

25 years	58.6 mm (2.3 in)
50 years	64.6 mm (2.5 in)
100 years	70.6 mm (2.8 in)	Longer than the 81 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 81 years of values from 1936 to 2018.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 65.7 mm (2.6 in) in 2004; 62.3 mm (2.5 in) in 1967; 62.1 mm (2.4 in) in 2000.

Station Changes

3 suspected

3 changes were suspected in the annual mean temperature of Mozajsk, at 1972, 1992 and 2011. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1972 ran 0.1 C (0.3 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1992 ran 0.2 C (0.3 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2011 ran 0.1 C (0.2 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Mozajsk, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1972	-0.1	-0.3	likely	5
1992	+0.2	+0.3	likely	5
2011	+0.1	+0.2	possible	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.

Climate Twins

2004 to 2018 against 1961 to 1990

Over 2004 to 2018, Mozajsk had a mean temperature of 5.9 C (42.5 F) and 670.7 mm (26.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Trubcevsk (Russia, 353 km away), Krasnaja_Gora (Russia, 399 km away) and Kursk (Russia, 415 km away).

Climate twins of Mozajsk: stations whose 1961 to 1990 climate is closest to its 2004 to 2018 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Trubcevsk	Russia	353 km (219 mi)	5.8 C (42.4 F)	644.0 mm (25.4 in)	0.65
Krasnaja_Gora	Russia	399 km (248 mi)	6.0 C (42.9 F)	607.7 mm (23.9 in)	0.70
Kursk	Russia	415 km (258 mi)	5.9 C (42.5 F)	607.2 mm (23.9 in)	0.80

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
