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

77 years with a frost

Across 77 years with a frost, the median last spring frost at Frolovo falls on 24 April and the median first autumn frost on 3 October, which leaves a median of 161 days between them.

In 1989 to 2018 the median growing season was 161 days. The two periods have the same number of growing days.

Fitted over all years, the growing season changes by +0.3 days per decade at this station.

First autumn frost3 October1 October4 October3 days later+0.1 days per decade
Growing days161 days161 days161 daysno change+0.3 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 2018

A day with at least 30.2 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 83.6 mm (3.3 in) of rain is expected about once in 100 years.

50 years73.3 mm (2.9 in)
100 years83.6 mm (3.3 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: 87.1 mm (3.4 in) in 1973; 72.5 mm (2.9 in) in 1966; 70.0 mm (2.8 in) in 1955.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Frolovo, at 2008. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 2008 ran 0.2 C (0.3 F) lower than in the years before (possible change).

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.

Climate Twins

2004 to 2018 against 1961 to 1990

Over 2004 to 2018, Frolovo had a mean temperature of 8.7 C (47.6 F) and 442.6 mm (17.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Volshskiy Gmo (Russia, 137 km away), Cimljansk (Russia, 268 km away) and Verhnij_Baskuncak (Russia, 282 km away).

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.
