- | **Main Objectiv**: \\ | ||
- | * To quantify climate change impact on technical infrastructure and the natural environment caused by strong winds, icing and wet snow.\\ | ||
- | \\ | ||
- | **Sub-objectives: | ||
- | * To improve the description of cloud microphysical processes of importance for simulating atmospheric icing. \\ | ||
- | * To quantitatively assess future wind and ice design loads on electric transmission lines in different geographical regions in Norway. \\ | ||

- | **Project Summary** \\ | ||
- | \\ | ||
- | Strong winds, atmospheric icing and heavy snowfall are weather phenomena that can cause severe | ||
- | damage to technical infrastructure such as the electric power grid as well as natural environments | ||
- | such as forests. The objective of WISLINE is to improve predictions and design values of | ||
- | atmospheric icing, heavy snowfall and damaging winds in the current climate, and to provide | ||
- | quantitative estimates of changes in these parameters in the future, for evaluating the changing risks | ||
- | of forest wind throw and disruption of technical infrastructures, | ||
- | In order to meet this objective, the project will: 1) Improve the description of physical processes in | ||
- | the atmospheric models, enabling a better quantification of icing and heavy snowfall events; 2) | ||
- | Establish improved post-processing and bias-correction methods for better assessment of icing and | ||
- | damaging winds. That will serve as input to impact models for analysis of icing on electricity | ||
- | transmission lines and wind-throw and breakage in forest stands in a future climate. 3) Apply the | ||
- | improved physical parameterizations, | ||
- | high-resolution simulations of icing conditions and damaging winds in future climates; 4) Develop | ||
- | post-processing tools that can enable users to make better decisions with respect to future weather | ||
- | challenges. All datasets and results of WISLINE will be open to end-users (scientists, | ||
- | management, infrastructure owners, planners, and the public). Open access to data will be made | ||
- | available through data distribution systems operated by MET in order to support public and private | ||
- | sectors to adapt to climate change. MET Norway will through its core mandate, extend the results | ||
- | demonstrated in the project into its base datasets for current and future climate in Norway. | ||
