Influence of changes in topography on Northern Hemisphere atmospheric dynamics during interglacial and glacial times ...
During the Quaternary Period, i.e., the last 2.6 Ma, the climate on Earth has alternated between warm phases, so-called interglacials, and cold intervals, termed glacials. The resulting glacial–interglacial cycles are observed in many climate archives such as ocean sediments and Antarctic ice cores...

| Summary: | During the Quaternary Period, i.e., the last 2.6 Ma, the climate on Earth has alternated between warm phases, so-called interglacials, and cold intervals, termed glacials. The resulting glacial–interglacial cycles are observed in many climate archives such as ocean sediments and Antarctic ice cores and express themselves in terms of, e.g., atmospheric and oceanic temperatures, atmospheric composition, and global sea level. Despite the impressive amount of data gathered from paleoclimate reconstructions, profound knowledge about the evolution of atmospheric dynamics over these time scales is still rare as many features of the atmospheric circulation are hardly (if at all) possible to be reconstructed from proxy data. Therefore, estimating the sensitivity of the atmospheric circulation to glacial and interglacial boundary conditions is an important research topic for the climate modelling community. One key element, which considerably varies between glacial and interglacial states, is the global distribution ... |
