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 Jiuquan falls on 23 April and the median first autumn frost on 10 October, which leaves a median of 170 days between them.
In 1988 to 2024 the median growing season was 173 days. That is 3 days more than in 1951 to 1980.
Fitted over all years, the growing season changes by +1.7 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
66 years, 1951 to 2023
A day with at least 13.4 mm (0.5 in) of rain is expected about once in 2 years. A day with at least 54.3 mm (2.1 in) of rain is expected about once in 100 years.

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 1951 to 2023.
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: 44.2 mm (1.7 in) in 1983; 39.0 mm (1.5 in) in 1964; 36.8 mm (1.4 in) in 1967.
Climate Twins
2003 to 2024 against 1961 to 1990
Over 2003 to 2024, Jiuquan had a mean temperature of 8.9 C (48.1 F) and 91.3 mm (3.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Yinchuan (China, 681 km away), Minqin (China, 416 km away) and Dunhuang (China, 327 km away).
Climate twins of Jiuquan: stations whose 1961 to 1990 climate is closest to its 2003 to 2024 climate
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.
