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.

Frost Dates and Growing Season

67 years with a frost

Across 67 years with a frost, the median last spring frost at Jaransk falls on 22 May and the median first autumn frost on 17 September, which leaves a median of 114 days between them.

In 1989 to 2018 the median growing season was 115 days. That is 1 day more than in 1936 to 1981.

Fitted over all years, the growing season changes by 0.0 days per decade at this station.

Frost dates and growing season at Jaransk
Measure	Median, all years	Earliest period (1936 to 1981)	Recent period (1989 to 2018)	Recent against earliest	Fitted trend
Last spring frost	22 May	24 May	22 May	2 days earlier	+0.1 days per decade
First autumn frost	17 September	17 September	17 September	no change	+0.1 days per decade
Growing days	114 days	114 days	115 days	1 day more	0.0 days per decade

A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.

Rainfall Return Levels

66 years, 1936 to 2018

A day with at least 31.6 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 70.5 mm (2.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Jaransk: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	31.6 mm (1.2 in)
5 years	42.5 mm (1.7 in)
10 years	49.5 mm (1.9 in)
25 years	58.1 mm (2.3 in)
50 years	64.4 mm (2.5 in)
100 years	70.5 mm (2.8 in)	Longer than the 66 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, 66 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: 62.3 mm (2.5 in) in 1977; 59.5 mm (2.3 in) in 1978; 59.5 mm (2.3 in) in 2012.

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.
