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.

Rainfall Return Levels

66 years, 1951 to 2024

A day with at least 91.9 mm (3.6 in) of rain is expected about once in 2 years. A day with at least 234.2 mm (9.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Yibin: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	91.9 mm (3.6 in)
5 years	126.2 mm (5.0 in)
10 years	150.3 mm (5.9 in)
25 years	182.6 mm (7.2 in)
50 years	207.9 mm (8.2 in)
100 years	234.2 mm (9.2 in)	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 2024.

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: 221.9 mm (8.7 in) in 1991; 191.8 mm (7.6 in) in 1974; 187.7 mm (7.4 in) in 1984.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Yibin, at 1957. Each is measured against neighbouring stations.

Relative to 4 neighbouring stations, the station's annual mean temperature from 1957 ran 0.4 C (0.7 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Yibin, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1957	-0.4	-0.7	likely	4

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 2025 against 1961 to 1990

Over 2004 to 2025, Yibin had a mean temperature of 19.1 C (66.5 F) and 963.5 mm (37.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Smithville (United States, 13,080 km away), Somerville Dam (United States, 13,068 km away) and Fairfield 3W (United States, 12,934 km away).

Climate twins of Yibin: stations whose 1961 to 1990 climate is closest to its 2004 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Smithville	United States	13,080 km (8,128 mi)	19.4 C (66.8 F)	959.4 mm (37.8 in)	0.56
Somerville Dam	United States	13,068 km (8,120 mi)	19.4 C (67.0 F)	938.9 mm (37.0 in)	0.64
Fairfield 3W	United States	12,934 km (8,037 mi)	19.2 C (66.5 F)	1,027.8 mm (40.5 in)	0.64

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.
