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 Ruoqiang falls on 3 April and the median first autumn frost on 17 October, which leaves a median of 197 days between them.

In 1986 to 2022 the median growing season was 203 days. That is 8 days more than in 1953 to 1982.

Fitted over all years, the growing season changes by +2.2 days per decade at this station.

Frost dates and growing season at Ruoqiang
Measure	Median, all years	Earliest period (1953 to 1982)	Recent period (1986 to 2022)	Recent against earliest	Fitted trend
Last spring frost	3 April	7 April	29 March	9 days earlier	-2.0 days per decade
First autumn frost	17 October	20 October	17 October	3 days earlier	+0.2 days per decade
Growing days	197 days	195 days	203 days	8 days more	+2.2 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

63 years, 1953 to 2022

A day with at least 7.5 mm (0.30 in) of rain is expected about once in 2 years. A day with at least 65.6 mm (2.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Ruoqiang: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	7.5 mm (0.30 in)
5 years	14.4 mm (0.6 in)
10 years	21.4 mm (0.8 in)
25 years	34.1 mm (1.3 in)
50 years	47.5 mm (1.9 in)
100 years	65.6 mm (2.6 in)	Longer than the 63 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, 63 years of values from 1953 to 2022.

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: 73.5 mm (2.9 in) in 1981; 52.0 mm (2.0 in) in 2005; 40.0 mm (1.6 in) in 1988.
