The fitted trend in annual mean temperature here over 1905 to 1971 is 0.05 C (-0.08 to 0.17) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.1 F (-0.1 to 0.3) per decade. The slope is a straight line fitted to 63 complete years; the brackets give its 95 percent interval.

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

63 years with a frost

Across 63 years with a frost, the median last spring frost at Riksgransen falls on 11 June and the median first autumn frost on 13 September, which leaves a median of 95 days between them.

In 1942 to 1971 the median growing season was 96 days. That is 6 days more than in 1905 to 1938.

Fitted over all years, the growing season changes by +4.0 days per decade at this station.

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

64 years, 1905 to 1972

A day with at least 39.3 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 102.6 mm (4.0 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 64 years of values from 1905 to 1972.

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: 107.4 mm (4.2 in) in 1959; 81.7 mm (3.2 in) in 1964; 76.5 mm (3.0 in) in 1917.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Riksgransen, at 1911. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1911 ran 0.4 C (0.8 F) higher than in the years before (possible change).

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.
