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

49 years with a frost

Across 49 years with a frost, the median last spring frost at Presa Danxho falls on 10 March and the median first autumn frost on 24 October, which leaves a median of 218 days between them.

Fitted over all years, the growing season changes by -5.8 days per decade at this station.

Frost dates and growing season at Presa Danxho
Measure	Median, all years	Earliest period	Recent period (1972 to 2010)	Recent against earliest	Fitted trend
Last spring frost	10 March	n/a	18 March	n/a	+3.1 days per decade
First autumn frost	24 October	n/a	24 October	n/a	-2.8 days per decade
Growing days	218 days	n/a	215 days	n/a	-5.8 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

58 years, 1951 to 2010

A day with at least 50.3 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 86.5 mm (3.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Presa Danxho: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	50.3 mm (2.0 in)
5 years	61.7 mm (2.4 in)
10 years	68.5 mm (2.7 in)
25 years	76.3 mm (3.0 in)
50 years	81.7 mm (3.2 in)
100 years	86.5 mm (3.4 in)	Longer than the 58 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, 58 years of values from 1951 to 2010.

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: 97.3 mm (3.8 in) in 1999; 74.9 mm (2.9 in) in 1955; 73.4 mm (2.9 in) in 1996.

Station Changes

3 suspected

3 changes were suspected in the annual mean temperature of Presa Danxho, at 1972, 1978 and 1994. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1972 ran 1.2 C (2.1 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1978 ran 4.4 C (8.0 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1994 ran 1.0 C (1.8 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Presa Danxho, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1972	+1.2	+2.1	likely	5
1978	-4.4	-8.0	likely	5
1994	-1.0	-1.8	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.
