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
80 years with a frostAcross 80 years with a frost, the median last spring frost at Ust-Ozernoe falls on 23 May and the median first autumn frost on 11 September, which leaves a median of 110 days between them.
In 1988 to 2018 the median growing season was 113 days. That is 5 days more than in 1936 to 1967.
Fitted over all years, the growing season changes by +1.1 days per decade at this station.
| Measure | Median, all years | Earliest period (1936 to 1967) | Recent period (1988 to 2018) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 23 May | 23 May | 22 May | 1 day earlier | -0.4 days per decade |
| First autumn frost | 11 September | 8 September | 11 September | 3 days later | +0.7 days per decade |
| Growing days | 110 days | 108 days | 113 days | 5 days more | +1.1 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
82 years, 1936 to 2018A day with at least 27.3 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 78.0 mm (3.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 27.3 mm (1.1 in) | |
| 5 years | 37.0 mm (1.5 in) | |
| 10 years | 44.7 mm (1.8 in) | |
| 25 years | 56.2 mm (2.2 in) | |
| 50 years | 66.4 mm (2.6 in) | |
| 100 years | 78.0 mm (3.1 in) | Longer than the 82 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, 82 years of values from 1936 to 2018.
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: 95.7 mm (3.8 in) in 1940; 73.0 mm (2.9 in) in 1994; 65.1 mm (2.6 in) in 2015.
Climate Twins
2004 to 2018 against 1961 to 1990Over 2004 to 2018, Ust-Ozernoe had a mean temperature of -0.4 C (31.3 F) and 531.5 mm (20.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Sredny Vasjugan (Russia, 547 km away), Kyra (Russia, 1,868 km away) and Nizhneudinsk (Russia, 815 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Sredny Vasjugan | Russia | 547 km (340 mi) | -0.6 C (30.9 F) | 537.2 mm (21.1 in) | 0.95 |
| Kyra | Russia | 1,868 km (1,161 mi) | -0.4 C (31.2 F) | 376.5 mm (14.8 in) | 1.09 |
| Nizhneudinsk | Russia | 815 km (506 mi) | -0.6 C (30.9 F) | 393.4 mm (15.5 in) | 1.10 |
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.
