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
60 years with a frostAcross 60 years with a frost, the median last spring frost at Bayan Mod falls on 29 April and the median first autumn frost on 7 October, which leaves a median of 160 days between them.
In 1987 to 2025 the median growing season was 166 days. That is 8 days more than in 1957 to 1986.
Fitted over all years, the growing season changes by +1.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1957 to 1986) | Recent period (1987 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 29 April | 1 May | 27 April | 4 days earlier | -0.5 days per decade |
| First autumn frost | 7 October | 6 October | 8 October | 2 days later | +1.0 days per decade |
| Growing days | 160 days | 158 days | 166 days | 8 days more | +1.5 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, 1957 to 2021A day with at least 18.9 mm (0.7 in) of rain is expected about once in 2 years. A day with at least 53.4 mm (2.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 18.9 mm (0.7 in) | |
| 5 years | 28.2 mm (1.1 in) | |
| 10 years | 34.4 mm (1.4 in) | |
| 25 years | 42.1 mm (1.7 in) | |
| 50 years | 47.8 mm (1.9 in) | |
| 100 years | 53.4 mm (2.1 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 1957 to 2021.
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: 46.8 mm (1.8 in) in 2010; 44.0 mm (1.7 in) in 1998; 42.7 mm (1.7 in) in 2004.
Climate Twins
2002 to 2025 against 1961 to 1990Over 2002 to 2025, Bayan Mod had a mean temperature of 8.3 C (47.0 F) and 128.3 mm (5.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Jartai (China, 151 km away), Minqin (China, 265 km away) and Ouray 4NE (United States, 10,381 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Jartai | China | 151 km (94 mi) | 9.2 C (48.5 F) | 103.1 mm (4.1 in) | 0.96 |
| Minqin | China | 265 km (165 mi) | 8.4 C (47.0 F) | 110.7 mm (4.4 in) | 1.28 |
| Ouray 4NE | United States | 10,381 km (6,450 mi) | 8.3 C (46.9 F) | 161.6 mm (6.4 in) | 1.32 |
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.
