While narratives or storylines have been used for decades in social sciences and beyond (e.g. RCPs, SSPs, economic risk assessment), the concept of analyzing and communicating high-impact weather extreme events in the climate change context via storylines has recently gained quite some popularity in the climate modeling community.
For instance, the use of case studies or storylines that could illustrate climate risk narratives has been discussed in the recent IPCC expert meeting for regional climate information. This also calls for an expert discussion on challenges/pitfalls and best practices for the creation of credible storylines of high-impact weather or climate features using (high-resolution) physical modeling and knowledge creation.
The storyline approach is believed to support the decision-making process by explicitly referring to personalized experiences with recent events, or creating unprecedented combinations of conditions that may aggravate the impact of weather events. Further, storylines can help to describe and understand complex interactions between the physical, ecological, economic and societal aspects of climate change related to a specific extreme or compound event.
As an example, in the TWEX project, model experiments have been performed to simulate one particular storyline about a high-impact flooding event in Norway based on current process-understanding. Particular emphasis was given on exploiting a full model chain from a high-resolution Earth System model to a convection permitting Numerical Weather Prediction model to hydrological impact modeling. Various challenges as well as surprises have been experienced when simulating such a very localized event under present and future conditions.
Storylines are also a useful way to investigate and communicate compound events, which are in the focus of the COST Action (CA17109) DAMOCLES “Understanding and modeling compound climate and weather events”.
As a cross-Working Group meeting of DAMOCLES, this meeting is funded by COST.
The outcome of the workshop will provide a critical component to the implementation of the WCRP Strategic Plan 2019-2028, in support of innovation in the generation of decision-relevant information and knowledge about the evolving Earth system through the framework of the WCRP Grand Challenge on Weather and Climate Extremes.
In this workshop, several examples of physical modeling supporting a storyline approach will be presented and discussed. The range of topics to be covered should include:
- How can storylines or narratives of specific events be combined with probabilistic approaches?
- What kind of models (GCM, RCM, convection-permitting, impact models) are required to support the storyline approach, and are useful to include in a model chain approach?
- What should be considered when designing the model experiments for localized events (e.g., resolution, ensemble size and design, choice of scenario/forcing/initial conditions)?
- What are the challenges and advantages of this storyline approach (basically picking a particular event) compared to the full probabilistic approach? And how does it differ or compare with other storyline approaches (e.g. SSPs)?
- What are useful approaches to combine physical with statistical modeling and the knowledge from other domains (e.g., social sciences, impact modeling)?
The outcome of the workshop will be a peer-reviewed paper, providing a perspective on best-practice of physical modeling to accompany narratives of high-impact extreme and compound events and associated risks under climate change; assuming that storylines are a useful communication tool to connect climate information to decision making.
Session 1, in the afternoon on Wednesday 24 April:
Examples of projects that have used case studies and provide insights in success stories or challenges with the storyline approach
(invited speakers: Julia Slingo, Douglas Maraun, Alex Hall, Andreas Zischg)
Session 2, in the morning on Thursday 25 April:
Presentations on how to generalize storylines, develop generic or sector-based approaches for different decision making contexts
(invited speakers: Reinhard Mechler (finance), Trine Hegdahl (flood warning), Gordon Woo (insurance))
Session 3, in the afternoon on Thursday 25 April:
Likelihood of storylines
What are different approaches to likelihood (quantitative/qualitative) that can be applied in a storyline? Can storylines be useful without a likelihood attached?
(invited speakers: Lisa Lloyd and Liese Coulter)
Session 4, in the morning on Friday 26 April:
Combining multiple sources of information
How to fit storylines in the current landscape of climate and impact data sources (i.e. multi-model intercomparison projects, such as ISIMIP (ISIPEDIA), CORDEX, CMIP)? How to make use of those large data pools for storyline development and combine information from multiple sources?
(invited speakers: Detlef van Vuuren, Adam Sobel)
Session 5, in the afternoon on Friday 26 April:
Conclusion/Outlook (the workshop ends around 14:30).
The workshop will be held at Oslo Science Park. Click here for information on how to get here from the Oslo city centre and from Oslo's main airport, Oslo Lufthavn Gardermoen.
Arrival in Oslo and airport transfer:
Oslo's only airport, Oslo Lufthavn Gardermoen, is located 45 km from the city centre. The fastest way to downtown Oslo is by Flytoget, the airport express train, which takes you to the city center in 20 minutes. A one-way ticket costs NOK 190 and you can buy them at the orange ticket machines or the Flytoget app. Trains run every ten minutes from 05:35 to 00:35.
However, the cheapest way to get to the city centre is to take the regional train (NSB) that connects the airport with Oslo S (the main railway station). The price is NOK 101 and the journey takes 23 minutes. You can buy tickets for this train on the red ticket machines, or on the NSB app.
