Location: SISSA Room A

Conveners: members of three weather services, Deutscher Wetterdienst (D), GeoSphere Austria (A), and MeteoSwiss (CH) Nora Leps, Theresa Shellander-Gorgas, Sven Kotlarski

This session is devoted to the use of GWL-methods in the context of CORDEX. Short presentations will cover GWL approaches with focus on regional simulations and climate services. Experiences with communicating the regional interpretation of GWLs are welcome. Ideally, the discussion will result in a recommended approach to compute and use GWLs in the CORDEX community. Hybrid session with no limit to number of participants.

Session report

Detailed program

14.30 – 15.30 10 min General introduction to the session and 3 talks (12+3 min each)
Reference trajectory for adaptation in metropolitan France: describing the impact of global warming levels at the local scale. Lola CORRE
Deriving GWL-based products for modern climate services Harald RYBKA
Developing a concept for GWL with users – Experiences from the NUKLEUS project Kevin SIECK 

15.30 – 16.00: Health break

16.00 – 17.00: Moderated discussion addressing the following questions:
1) What are the main challenges in generating GWL-based climate information at the local/regional scale?
2) Which approaches do exist and which are their respective pros and cons?
3) Do groups/service providers already have specific experiences with the acceptance of users regarding GWL-based climate information?
4) Which are the difficulties arising for users of (formerly) transient climate data and are there ways to avoid these complications?
5) Can we identify common findings which could be used for some general recommendations for deriving GWL-based products (e.g. for other services)?

Due to unforeseen circumstances some speakers may be replaced or will not be able to participate.
