Info

Frosty days The number of days in a year with temperatures below freezing point. Growing season The length of the growing season constitutes the number of days from the first six consecutive days with daily average temperatures above 5°C to the last six consecutive days with daily average temperatures above 5°C. Hot summer nights The number of summer nights in a year with night temperatures above 20°C. Precipitation events > 10mm The number of days in a year with more than 10mm of precipitation. Precipitation events > 20mm The number of days in a year with more than 20mm of precipitation. Annual highest day total The total volume of precipitation during the day in a year that has the most precipitation in the grid point where the value is greatest. Annual highest five-day total The total volume of precipitation during the five consecutive days in a year that have the most precipitation averaged across Denmark. Mean intensity, precipitation The average precipitation for all days with more than 1mm of daily precipitation. Heatwave days The number of annual national heatwave days. The definition of a heatwave is when the highest recorded temperatures observed over three consecutive days on average exceed 28°C. A national heatwave is when at least half of Denmark is experiencing a heatwave. Longest heatwave The length of the longest heatwave averaged over a 30-year period. Warm spell days The number of annual national warm spell days. The definition of a warm spell is when the highest recorded temperatures observed over three consecutive days on average exceed 25°C. A national warm spell is when at least half of Denmark is experiencing a warm spell. Longest warm spell The length of the longest warm spell averaged over a 30-year period. 3.4 Regular updating of data sets for use in climate-change adaptation efforts The current data presented above, which informs climate change adaptation efforts, are based on the IPCC's SRES scenarios. There is need for continuous updating of these data sets that underpin local 20
climate change adaptation initiatives and upcoming action plans. Without such updating, Danish climate change decisions would soon have to be based on outdated data. A number of model experiments with the new RCP scenarios are being performed at present, leading up to the IPCC's fifth assessment report with global climate models. Extensive global-scale model data will therefore be available soon with the new scenarios, and the data sets informing Danish climate change adaptation efforts should therefore be updated regularly to reflect the most recent knowledge. However, future Danish climate change adaptation efforts should continue to be based also on regional models, including the Danish HIRHAM model, which has been verified and tested meticulously for Danish conditions. Global models do not provide the necessary resolution and quality of data for the Danish region. Similarly, it will be necessary to update the data sets for the impacts of climate change on the water cycle. With a new information basis in terms of climate models and RCPs, as well as continuous improvements to the national water resources model (the DK Model), it will be possible to reduce the uncertainties linked to predicting the climate impacts on groundwater recharge and groundwater level as well as on surface water, including flooding. No doubt we will be able to achieve an ever better understanding of the data needed in local and sector-specific climate change adaptation efforts, as well as how to provide further data to meet these needs. 21
