Climate Change Chart of Sölden, Austria

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +2.88 °C compared with the earlier reference period; this is an unweighted average of monthly means, not a day-weighted annual figure or a measure of daytime maximum temperatures. The largest monthly increase was in December, with a difference of +7.71 °C. This identifies the strongest increase among the reported monthly differences, rather than describing every month.

Changes in snowfall

Mean daily snowfall, not monthly totals, had an average difference of +3.87 mm/day across calendar months. This is an unweighted summary of monthly means, so it does not describe the change in every month. Among the reported monthly differences, October had the largest increase in mean daily snowfall, with a difference of +8.43 mm/day. The largest decrease was in June, at a difference of -2.73 mm/day; these contrasting monthly changes show why the average does not capture each month's result.

Changes in rainfall

Mean daily rainfall, rather than monthly rainfall totals, had an average difference of -0.27 mm/day across calendar months. This unweighted mean summarizes the monthly differences and does not imply the same change in each month. The largest monthly decrease occurred in July, with a difference of -1.01 mm/day in mean daily rainfall. By contrast, October recorded the largest increase, a difference of +0.20 mm/day; these are the respective monthly extremes, not a complete account of rainfall changes throughout the year.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of -0.15 hours/day. This unweighted summary of monthly means does not mean that sunshine duration declined in every month. The monthly differences were mixed: May had the largest decrease, a difference of -0.72 hours/day, while June had the largest increase, a difference of +0.65 hours/day in mean daily sunshine duration.
