- Abstract
- Global mean temperature has been observed to increase over the last hundred years; this increase is coupled with a global increase of warm extreme indices and a decrease in cold extreme indices. In this study, daily observations of mean and extreme temperatures from ten different weather stations in Sweden during the time period 1961-2010 were analyzed. A warming trend was identified for every data series for all stations at a statistical significance of 99.95% (with one exception at 99.9%). The tendencies differ between the stations where some show a higher increase in mean temperature while others a higher increase in extreme temperatures; the different rate of change is concluded to depend on local and regional weather effects.

The tendencies differ between the stations where some show a higher increase in mean temperature while others a higher increase in extreme temperatures; the different rate of change is concluded to depend on local and regional weather effects. Northern Sweden is compared to Southern Sweden and the stations in Northern Sweden show a higher warming in cold extreme temperatures (0.04°C/y on average) than in the warm extreme temperatures (0.028°C/y on average). In Southern Sweden there is a higher warming in the warm temperature extremes (0.037°C/y on average) compared to the cold temperature extremes (0.028°C/y on average). During the time period, the stations show an increase of the warm extreme temperatures of 0.8-2.3°C and 0.7-2.5°C for the cold extremes. (Less)
