The set is the 6 stations with at least 50 complete years (all twelve months with 20 or more days of maximum and minimum). A station's warmest year is the one with the highest annual mean temperature, a tie going to the later year. The count describes these stations, not the whole area.

Heavy Rain and Dry Spells by Decade: Denmark

5 stations in the annual rain series

In Denmark, annual rain at 5 stations is shown as a percent difference from each station's own 1961-1990 mean, for 60 years from 1961 to 2020.
The trend in annual rain is +2.0 percent per decade (95 percent interval +0.1 to +4.0), fitted to 60 years from 1961 to 2020.

Annual rain against the 1961-1990 mean

Annual rain in Denmark as a percent difference from each station's own 1961-1990 mean, for 5 stations with a long record, 1961 to 2020. Stations are averaged in 5 degree grid cells and the cells are weighted by the cosine of latitude.

The annual rain series uses stations with at least 50 complete years since 1951 and a 1961-1990 baseline. The decade charts use fixed sets of stations, the same in every decade from the 1960s. A dry day has less than 1 mm (0.04 in) of rain.

A run belongs to the year it started in, even when it ran on into the next year. A station appears once per list, with its longest run in a complete year. Dry and wet spells are the longest run within a year. Lists use complete years only, so a long run in a year with gaps in the record is not counted.
