Within the framework of the Helmholtz Network "Regional Climate Change" (REKLIM) nine Research Centres of the Helmholtz Association focus their competences in exploring the regional climate. The networks research activities will help to improve the understanding of regional processes and therefore contribute to optimise mitigation and adaptation strategies.
REKLIM is using its unique combination of competence in regional observations and process studies (in situ observations, airborne and satellite remote sensing) coupled with model simulations to improve regional and global climate models, which provide a solid basis for climate-related decision support. Moreover, global climate simulations are used to determine the effects of climate variability and change on the regional scale with improved modelling tools for attribution and impact studies. On the other hand, process modules and parameterisations from these regional studies serve to improve global climate models. The Climate Initiative will facilitate various scientific opportunities for improving knowledge of the regional Earth System, in particular with respect to impacts.
The networks research activities will help to improve the understanding of regional processes and therefore contribute to optimise mitigation and adaptation strategies.
GFZ and partners joined together in order to find answers to the following questions:
Topic 2: Sea-level changes and coastal protection (Section 1.2 & 1.3)
How large are the losses of the continental ice masses (particularly on Greenland) and how does the sea level react on melt water run-off and ocean warming?
Contact: Prof. Dr. Maik Thomas
Topic 3: Regional climate changes in the Arctic: Forcing and long-term effects at the land-ocean interface (Helmholtz-Nachwuchsgruppe TEAM /Section 1.4)
What specific changes result for land, ocean, and atmosphere in the shelf sea and permafrost regions of the Arctic are due to climate change and what interactions take place?
Contact: Prof. Torsten Sachs
Topic 4: The land surface in the climate system (Section 5.2, 5.4 & CGR)
What are the regional impacts of climate change on the ecosystem, water resources, agriculture, forestry and how do these in turn influence the climate?
Contact: Dr. Knut Kaiser
Topic 6: Extrem weather events - storms, heavy precipitation, floods and droughts (Section 5.4)
How will the severity and frequency of extreme weather events change in a future climate?
Contact: Prof. Dr. Bruno Merz
Topic 8: Abrupt climate change derived from proxy data (Section 5.2)
Which mechanisms, processes and regional climate patterns intensify abrupt climate changes during interglacials and at glacial-interglacial transitions? How different are these patterns compared to the last interglacial, the Eemian, when the average temperature was about 1-2°C higher than it is now?
Contact: Prof. Dr. Achim Brauer
