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

69 years with a frost

Across 69 years with a frost, the median last spring frost at Gleichen falls on 21 May and the median first autumn frost on 12 September, which leaves a median of 114 days between them.

In 1951 to 1983 the median growing season was 118 days. That is 8 days more than in 1904 to 1941.

Fitted over all years, the growing season changes by +2.8 days per decade at this station.

Frost dates and growing season at Gleichen
Measure	Median, all years	Earliest period (1904 to 1941)	Recent period (1951 to 1983)	Recent against earliest	Fitted trend
Last spring frost	21 May	28 May	19 May	9 days earlier	-1.7 days per decade
First autumn frost	12 September	10 September	15 September	5 days later	+1.1 days per decade
Growing days	114 days	110 days	118 days	8 days more	+2.8 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

69 years, 1903 to 1983

A day with at least 31.9 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 101.5 mm (4.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Gleichen: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	31.9 mm (1.3 in)
5 years	44.1 mm (1.7 in)
10 years	54.2 mm (2.1 in)
25 years	70.1 mm (2.8 in)
50 years	84.5 mm (3.3 in)
100 years	101.5 mm (4.0 in)	Longer than the 69 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, 69 years of values from 1903 to 1983.

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: 91.4 mm (3.6 in) in 1925; 83.6 mm (3.3 in) in 1947; 78.2 mm (3.1 in) in 1942.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Gleichen, at 1965 and 1979. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1965 ran 0.2 C (0.4 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1979 ran 0.6 C (1.0 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Gleichen, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1965	-0.2	-0.4	likely	5
1979	+0.6	+1.0	likely	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.
