The Helmholtz Climate Initiative 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.
Section 5.2 Climate Dynamics and Landscape Evolution participates in REKLIM in Topic 8 “Abrupt climate change derived from proxy data”.
Our main questions are: 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?
Topic 8 aims at identifying and explaining regional and temporal patterns of climate variability between the Pacific and Atlantic region as well as between lower and higher latitudes. The time span of the investigations encompasses the last 140.000 years and focusses on time scales from years to millennia. This time span allows scientists not only to analyze the rapid climate change during the last glacial termination and during the Holocene, but also to compare it to the second last glacial-interglacial transition and the following interglacial, the Eemian.
