Climate Trend

45 complete years, 1937 to 1986

One stripe for each of 45 complete years at Kauffman 4 SSE, 1937 to 1986. Blue stripes are years cooler than the station's own mean of 8.5 C (47.3 F); red stripes are warmer. The coolest year was 1951, at 6.9 C (44.4 F), and the warmest was 1954, at 9.9 C (49.8 F). The strongest colour marks a difference of 1.7 C (3.1 F).

The fitted trend in annual mean temperature here over 1937 to 1986 is 0.04 C (-0.09 to 0.18) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.1 F (-0.2 to 0.3) per decade. The slope is a straight line fitted to 45 complete years; the brackets give its 95 percent interval.

Fitted temperature trends per decade at Kauffman 4 SSE
Measure	Per decade (C)	Per decade (F)	Period	Complete years	Reading
Annual mean temperature	0.04 C (-0.09 to 0.18) per decade	0.1 F (-0.2 to 0.3) per decade	1937 to 1986	45	Not clearly different from zero
Mean daily maximum	-0.01 C (-0.19 to 0.18) per decade	-0.01 F (-0.35 to 0.32) per decade	1937 to 1986	45	Not clearly different from zero
Mean daily minimum	0.1 C (-0.1 to 0.3) per decade	0.2 F (-0.1 to 0.5) per decade	1937 to 1986	45	Not clearly different from zero

A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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

45 years with a frost

Across 45 years with a frost, the median last spring frost at Kauffman 4 SSE falls on 20 May and the median first autumn frost on 20 September, which leaves a median of 119 days between them.

Fitted over all years, the growing season changes by -0.4 days per decade at this station.

Frost dates and growing season at Kauffman 4 SSE
Measure	Median, all years	Earliest period	Recent period (1953 to 1986)	Recent against earliest	Fitted trend
Last spring frost	20 May	n/a	20 May	n/a	-0.1 days per decade
First autumn frost	20 September	n/a	20 September	n/a	-0.5 days per decade
Growing days	119 days	n/a	121 days	n/a	-0.4 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

47 years, 1937 to 1986

A day with at least 32.8 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 87.9 mm (3.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Kauffman 4 SSE: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	32.8 mm (1.3 in)
5 years	45.2 mm (1.8 in)
10 years	54.3 mm (2.1 in)
25 years	66.9 mm (2.6 in)
50 years	77.1 mm (3.0 in)	Longer than the 47 years of record
100 years	87.9 mm (3.5 in)	Longer than the 47 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, 47 years of values from 1937 to 1986.

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: 77.5 mm (3.1 in) in 1944; 71.1 mm (2.8 in) in 1963; 71.1 mm (2.8 in) in 1985.
